The Best Abandoned Places in Maryland
Mallows Bay (Nanjemoy)
Tucked away in a tiny bay along the Potomac is one of the world’s largest ship graveyards, a slowly-decaying testament to the most expensive shipbuilding endeavor in modern history.
Located just outside Nanjemoy, Mallows Bay contains the wrecks of nearly 230 vessels. The ships date back to the first World War, when the U.S. found itself in dire need of transport vessels for soldiers and supplies. With most available steel being dedicated to battleships, the fleet of steamships would be made of wood, but the construction deadline of 18 months was impossible for the shipbuilders to meet. By the time a peace agreement was signed in 1918, the hastily-built ships were nowhere near ready for delivery.
With steel once again readily available after the war, the demand for the wooden ships was virtually nonexistent. After two unsuccessful salvage efforts, it was determined that attempting to remove them was prohibitively expensive, and they were abandoned to rot in the bay.
After several decades, a campaign to clean up Mallows Bay revealed that due to their overwhelmingly organic construction material, the shipwrecks had done more good than harm to the aquatic environment. In fact, the partially-submerged vessels had become a thriving ecosystem for plant and animal life, so they will remain in place until the forces of nature completely absorb them.
Though a few of the ships are visible from shore, to get a better look at the magnitude of the doomed fleet, we recommend taking a kayak or canoe through the bay’s calm, murky waters. Be sure to visit this abandoned places in Maryland during high tide and use caution as you get close to the wrecks, as chunks of glass or metal may lurk just below the surface. For now, it sits as one of the many great abandoned places in Maryland.
Forest Haven Asylum (Fort Meade)
Like so many of the facilities opened in the early 20th century with the mission of providing compassionate care to individuals with mental illness or disability, the Forest Haven Asylum initially enjoyed a positive reputation in the District of Columbia, but it eventually became notorious for abuse and even death inflicted on those it was supposed to serve.
The asylum opened in 1925 with a progressive approach to treating children with mental illness, physical handicaps or other challenges that might prevent them from thriving in a traditional home and school environment. The 250-acre campus operated a working farm colony to provide residents with both practical skills and a sense of belonging to a larger community, and for several decades it seemed to succeed in that mission.
However, drastic reductions in funding during the 1960s quickly began to impact the quality of care at Forest Haven. Experienced staff were laid off and replaced with a smaller group of unqualified, poorly-compensated workers, and recreational programs for the residents were eliminated. As conditions deteriorated, the center’s overworked and underpaid employees passed their frustrations on to the patients in the form of physical and sexual abuse and neglect.
Some were also involved in ethically questionable—if not outright inhumane—medical experiments at the facility. The death rate among the patient population jumped, and the deceased were often processed in a basement morgue on-site and buried in unmarked graves on the property. By the time the Forest Haven Asylum closed its doors in 1991, hundreds of patients had met their deaths within its walls.
For 20 years, the sprawling campus has been abandoned and generally untouched, with more than 30 buildings experiencing various stages of vandalism and decay. A lone headstone stands in the burial field to memorialize the hundreds of nameless souls sent to their eternal rest on the property.
Holland Island (Toddville)
While the mythical “lost city” of Atlantis enjoys a vaunted place in human legend, far fewer people have heard of Holland Island, which actually was swallowed up by the waters of the Chesapeake Bay over the course of a century.
First inhabited in the 1600s, Holland Island quickly became one of the most populous islands in the region, with around 350 residents at the turn of the 20th century. The community depended almost entirely on the fishing industry for its economic sustenance, and the island included dozens of residences, a school, a church and a post office.
Starting around 1914, island residents began to notice the creeping effects of erosion, particularly on the island’s west side. As sea levels rose, the shoreline began to disappear into the ocean, and the last family left the island in 1918. Several of the main buildings, including the church, were relocated to the mainland as the tides continued their march across the helpless chunk of land. What was once solid ground morphed into marshland, and soon after became simply open water.
By the end of the 20th century, only one structure remained standing: a two-story residence that was completely surrounded by water at high tide. A severe storm demolished it in 2010, leaving only sparse areas of marsh and debris as evidence that the island ever existed. By 2012, no part of the island remained visible from above the surface of the bay, and the remains of the town continue to settle in their watery grave. Currently, this sits as one of the best abandoned places in Maryland.

Glenn Dale Hospital (Glenn Dale)
Though the coronavirus outbreak that ravaged the globe in 2020 has been most often compared to the Spanish flu epidemic of 1918, another highly contagious—yet often overlooked—disease once invoked public terror and killed millions over the course of human history: tuberculosis.
Alternately known as “consumption” and the “white plague,” tuberculosis has appeared in medical literature for centuries, but until the 1950s, doctors knew very little about how to effectively combat it. Prior to the successful introduction of antibiotics into tuberculosis treatment regimens, patients with the disease were often confined to dedicated hospitals and sanatoriums for months or even years.
During a particularly severe tuberculosis outbreak in the Washington, D.C. area in the early 1930s, overflowing hospitals led to the construction of the Glenn Dale Hospital, which opened in 1934 to treat and isolate patients to help slow the spread of the deadly disease.
At the time, the main approach to treating tuberculosis included exposing patients to plenty of sunlight and fresh air, so the 216-acre campus of Glenn Dale Hospital consisted of vast lawns, rooftop gardens and underground tunnels to permit patients and staff to move between the 23 buildings in the complex during bouts of inclement weather.
As the medical community learned more about the potency of antibiotics in their fight against the disease in the 1940s and 1950s, the patient count at Glenn Dale Hospital began to decline. In 1960, it was transformed into a nursing home and community health facility for the poor. It closed for good in 1982 when the cost of asbestos removal and other needed repairs proved prohibitively expensive and has been vacant ever since.
Despite periodic proposals to redevelop the property, the only activity over the last several decades has consisted of vandalism and brief visits from curious teenagers and urban explorers, all of whom must avoid the periodic police patrols in their attempts to infiltrate the abandoned campus.
A private security firm has since been enlisted to guard the site. However, if you’re a brave explorer looking for a rarely-explored option for abandoned places in Maryland, look no further than the Glenn Dale Hospital (but, as always, be careful).
Springfield State Hospital (Sykesville)
With the lone state-operated psychiatric hospital bursting at the seams, the Maryland State Legislature voted in 1894 to identify a site for a second facility and settled on Springfield, the estate of the Patterson-Brown family, which counted among its members both Governor Frank Brown and Betsy Patterson, who brought global notoriety to the family when she married Napoleon Bonaparte’s brother Jerome.
With the official asylum facility still under construction, Springfield State Hospital’s first patients moved into renovated farmhouses on the property in July 1896. The first buildings to be completed were the Men’s Group on the north end of the campus, followed by the Women’s Group to the south in 1900.
As new patients were admitted to the hospital, both the Men’s and Women’s Groups underwent significant expansions, and the campus also added the John Hubner Psychopathic Building and an Epileptic Colony. A massive farm on site fed both patients and staff, and a powerhouse was erected on the property to provide water for drinking, cooking, bathing and steam heating.
The first patients were received at the hospital in July 1896. Existing farm houses were renovated to accommodate those first patients while the hospital buildings were being constructed. The first phase of the building program was the Men’s Group, located in the northern section of the hospital grounds and completed in 1898. A Women’s Group, located at the southern end of the campus, followed in 1900.
As the hospital population rapidly expanded, additional buildings were erected, including the John Hubner Psychopathic Building, the Epileptic Colony, and significant expansions to the Men’s and Women’s Groups. Over the next half-century, multiple maintenance buildings, a firehouse and staff housing were also added to the sprawling complex.
By the mid-20th century, more than 3,000 patients crowded the hospital’s units, with insufficient staff to care for them all. The state’s largest daily newspaper, The Baltimore Sun, ran a scathing series of articles exposing neglect, abuse and other issues at state hospitals; as a result, funding to Springfield increased to facilitate construction of new buildings and renovations to older ones.
Around the same time, Springfield State Hospital incorporated a new treatment model for the mentally ill led by social worker Henrietta DeWitt, which called for the placement of patients in family or foster homes. The movement soon spread to other states, and combined with the improvements in the efficacy and availability of pharmaceutical treatments, many patients were discharged from state hospitals to live as members of the community.
In the 1980s, the state consolidated much of its diminished operation into newer, more efficient buildings on-site, abandoning most of the older historic structures. High levels of asbestos and other toxic materials have made demolition, remediation and renovation prohibitively expensive options, so they have simply sat vacant in close proximity to the parts of the facility still in use. Several of the older buildings were added to the National Register of Historic Places in 2000, protecting them from demolition but failing to free them from their frozen-in-time existence.
Maryland Gold Mine (Potomac)
Though you don’t often hear about gold prospectors striking it rich along the East Coast, a handful of successful mines did exist in the region during the mid- to late-19th century. One such mine was inadvertently discovered by a Union soldier washing pots and pans in a stream just outside Washington, D.C., although extracting the gold from the earth had to be postponed until after the Civil War had ended.
In 1867, the newly-formed Maryland Mine Company dug its first shaft, launching a mining operation that would continue through 1939. Though trace deposits of gold still exist in the area along the Potomac River, the mine’s yield was never enough to deliver a profit, and the site was abandoned.
Though time and the elements have been harsh to the structures, the partial remains of a wooden water tower, an old blacksmith shop and a circle of stone arches are still visible on the property, which is now considered a historic site. If you search carefully, you can also locate the sealed entrances to the mine shaft, which are mostly obscured by overgrown brush.
The easiest way to explore the site is from the Gold Mine Spur trailhead behind the Great Falls Tavern visitor center. The moderate hike is roughly three miles and passes a waterfall and other interesting scenery in addition to the ruins of the mine. Currently, this sits as one of the best abandoned places in Maryland.
Curtis Creek Ship Graveyard (Baltimore)
Though it doesn’t boast the eye-popping number of vessels abandoned in Mallows Bay, the Curtis Creek ship graveyard does offer an impressive diversity of shipwrecks, most of which saw far more marine action than any of the ill-fated wooden ships near Nanjemoy.
Located in Baltimore, Curtis Creek’s shallow waters contain roughly a dozen ships in various sizes and shapes. They include the three-masted schooner William T. Parker, which was abandoned off the coast of North Carolina in 1899 and ultimately drifted as far north as Maine before the winds shifted to send it back down the East Coast, where a tugboat finally towed it into Curtis Creek and left it there. The creek also holds a handful of wooden freight ships from World War I, a sidewheel steamer ferry named Emma Giles and a crumbling concrete barge.
With no current plans to empty Curtis Creek of its ghostly inhabitants, the vessels will likely remain there until they are completely reclaimed by the water. The ship graveyard can be seen from several vantage points, including the I-695 bridge. For a closer look, consider paying to launch your own boat from the Jaws Marina, which is in close proximity to the William T. Parker and several other wrecks.
Urban exploration of abandoned places in Maryland is no fun if one of your hands is occupied with a flashlight. Save yourself with a headlamp, one of the most versatile pieces of urbex gear. We highly recommend either the PETZL Actik Core, or the Black Diamond Wiz for those on a budget. For a complete breakdown, please view our headlamp buyer’s guide.
Klotz Throwing Company (Lonaconing)
Tucked in the mountainous region of western Maryland, this silk mill once provided a livelihood for 300 full-time employees prior to its closure in 1957. Surprisingly, little has changed since the last workers left the building more than 60 years ago; a peek through the window reveals shelves still stocked with their personal effects: shoes, combs, canisters of hair cream and empty food jars.
Rows of spindles where silk thread was produced are dotted with transistor radios, which ostensibly provided workers with news and entertainment as they clocked hours of repetitive labor.
The building has been owned by a private citizen named Herb Crawford for more than 40 years. Though Crawford was essentially tricked into purchasing the obsolete facility, he has kept it open by appointment to photographers and other visitors.
However, the building’s deterioration over time has become dire, and Crawford recently launched a fundraising campaign to help finance the repairs and maintenance of the historic mill so desperately needs. For now, tours of the site must be arranged directly through Crawford, who is generous with his time and the property, allowing curious visitors freedom to photograph and explore the three-story mill where time stands still. Currently, this sits as one of the best abandoned places in Maryland.
Winderbourne Mansion (Boyds)
This posh Victorian-era residence was built in 1884 by the wealthy and well-connected couple Enoch and Mary Totten. After seeing battle during the Civil War, Enoch became a respected Washington lawyer, while Mary counted among her extended family Wisconsin Senator Timothy Howe and his cousin and heir Elias Howe, best known for his improvements to the modern sewing machine.
The majestic home stood out not only for its size, but also its distinctive color: bright pink with dark rose trim. Both Tottens were passionate gardeners, importing exotic plants from across the globe that were maintained by a full-time staff.
Unfortunately, the home became known for tragedy as well: all three Totten children caught typhoid fever (probably from drinking contaminated water) and one did not survive the illness. Their daughter Edith, who ultimately became a medical doctor, saw her own child perish after sliding down and falling from a long bannister in the home.
A second family, the Pickrells, acquired the home in 1929, and it passed to their son Edward Pickrell Jr., who remained there until his death in 2004. In recent years, the residence has experienced significant neglect and decay, and Edward Jr.’s brother Paxton has attempted unsuccessfully to sell this example of great abandoned places in Maryland.
Currently, the abandoned nine-acre property is littered with old cars and overgrown gardens, while the home’s interior is strewn with ancient furniture, dusty magazines and outdated clothing.
Fort Carroll (Baltimore)
Centered in the midst of the Patapsco River, Fort Carroll was built in 1847 as an additional line of defense for the City of Baltimore. The man-made island features a massive, hexagonal concrete fortification, which was once armed with 30 cannons during the Spanish-American and Civil Wars.
However, the post never saw much combat, and all weapons were transferred to Fort Howard after World War I. After a brief period of use as an Army firing range and ship checkpoint during World War II, Fort Carroll was totally abandoned to the elements.
The former base is now almost completely covered with out-of-control trees, bushes and vines, which have created an ideal habitat for millions of migratory birds. The island is accessible via kayak or canoe, and ambitious paddlers can explore a few concrete hallways, the key bridge, a small porch and the remains of a lighthouse. This is an incredible example of one of the best abandoned places in Maryland.
Abandoned Hang Gliding Launch Pad (Smithsburg)
Built by local hang-gliding enthusiasts, this defunct launch pad is located atop Mount Quirauk in Smithburg’s Pen-Mar Park. The site offered a rare location with a sufficiently high, sheer drop-off that would allow gliders to soar over the scenic countryside before floating safely to Earth.
Unfortunately for the gliding community, local officials determined that the launch spot wasn’t safe enough for everyday use, so gliders can only launch from the site after securing a special permit.
Still, this overlook along the Appalachian Trail gets plenty of hiking traffic due to the spectacular views it affords from 2,145 feet. Known as High Rock, the site is decorated with colorful graffiti despite its proximity to a Department of Defense radio communication outpost that is typically watched closely by Maryland State Police.
Cameras, headlamps, respirators and more. Urban exploration can be very gear-heavy, especially when exploring abandoned places in Maryland. When this is the case, it’s important to have a good-quality backpack. We recommend both the Osprey Packs Daylite for sling backpacks or the Mardingtop Tactical Backpack for a standard two-strap backpack. Alternatively, check out our comprehensive guide for far more options, tips, and tricks.
Thistle Mill Houses (Ellicott City)
When it was constructed in 1824, Thistle Mill represented a significant shift in the industrial economy of the Patapsco Valley, as cotton began to replace wheat as the mills’ main product.
In fact, when the Ellicott family—who then dominated the grist milling activity in the region—agreed to sell the property for Thistle Mill to business partners Alexander Fridge and William Morris in 1823, the deed included language prohibiting the site from being used for wheat milling to prevent any unwanted competition for the Ellicott dynasty.
Fortunately for the new property owners, the textile industry was poised to take off in the American South and would continue to fuel the Industrial Revolution for decades to come.
Even as the dynamics of human labor shifted dramatically with the abolition of slavery after the Civil War, cotton remained a lucrative product, and Thistle Mill continued to produce it until 1928, when the facility transitioned to paper production. It finally ceased operations in 2003, at which point it was being used primarily for cardboard recycling activities.
Though the mill facility itself was demolished over the decade following its closure, many of the residences the company established for employees over its 150-year history are still standing, albeit in varying states of decay and disarray.
Despite frequent flooding from the rise of the Patapsco River, the homes have survived due to their location on a parcel of land uphill from the former mill site. The boxy wood homes are surrounded by thick brush and fallen limbs and covered in green mildew. Most of the windows have been broken, and only a few have been patched with plywood.
Barring any concerted effort by local officials to tear them down, the old houses will likely continue their slow surrender to the forces of nature and time. For now, they are the only visible reminder of the milling industry that once served as the lifeblood of the Patapsco Valley.
Ocean City Drive-In (Ocean City)
Built at the drive-in theater’s peak popularity in the country, the Ocean City Drive-In opened to thrilled local residents in 1954. With room for 500 vehicles, the theater was a sought-after destination for date nights, family outings and cinephiles hoping to catch the latest Hollywood horror flick. When its screen lit up for the first time, it was one of nearly 4,000 drive-in theaters in operation across the U.S., and it remained a regional hot spot for the next 20 years.
The Ocean City Drive-In went dark in 1976, as trends shifted toward the traditional sit-down theaters that dominate the industry today. However, its now-faded iconic sign along Route 50 is still visible from the thick brush along the east side of the roadway, marking the abandoned remains of the theater.
The property is muddy and overgrown, and the crumbling concession stand and ticket booth are hanging on by a thread. The vast screen is still standing, though it can be hard to see in its hiding spot in the dense woods. The rusted skeleton of the old marquee sign slumps into the overgrowth, boasting a barely-visible “For Sale” sign that has apparently drawn little interest over the years.
Uplands Mansion (Baltimore)
Built in 1850, this lavish 42-room Victorian mansion was originally the summer home for wealthy socialite Mary Frick Garrett and her husband Robert Garrett, president of the Baltimore & Ohio Railroad. The Garretts divided their time between Uplands and their other residences in Rhode Island, Mount Vernon and Bar Harbor, traveling with a 35-member staff of servants and laborers.
After her husband died in 1896, Mrs. Garrett began staying at Uplands full-time, later marrying the physician who had cared for her former husband during his battle with kidney disease, Henry Barton Jacobs. They lived in the Baltimore mansion until 1929, and upon her death in 1936, Mary Jacobs left a $5.5 million estate to her husband. Not included in that inheritance was the Uplands estate, which she willed to the Protestant Episcopal Church along with a $1 million endowment.
Jacobs’ will specified that the mansion was to be modernized with the installation of electric lighting and power and converted into “a home for lonely churchwomen, unable to provide, in whole or part, for their own maintenance and support.”
However, the process of fulfilling her wishes took years longer than Jacobs could have imagined; disagreements among Protestant Episcopal Church leadership about the cost-effectiveness of improvements needed to make the residence suitable as a nursing home prevented any progress from being made toward Jacobs’ vision until 1950.
The Consolidated Engineering Company of Baltimore was enlisted to replace the clapboard exterior with stucco, add a fireproof annex to the building to house 36 resident bedrooms and renovate the existing structure to incorporate a dining room, library, chapel, kitchen and solarium as well as staff living quarters. At a cost of more than $531,000, the work took more than two years to complete, and the Uplands Home for Church Women finally welcomed its first residents in 1952.
After 32 years in operation, Uplands stopped accepting new residents and began gradually relocating its current tenants to the full-service Fairhaven retirement community near Sykesville. The former mansion was sold in 1986 to New Psalmist Baptist Church, which reportedly wanted to build a new church building on the site to accommodate its rapidly-growing congregation.
The church received approval for its $7.5 million construction project in 1993, which included building a new facility to connect to the existing structure. The new 2,000-person sanctuary opened in 1996, but the church soon outgrew it, and the congregation opted to relocate to a 33-acre property in the Seton Business Park.
The newly-constructed sanctuary was demolished as part of a city redevelopment plan to build affordable housing units on the site, but the old mansion component was spared, leaving open the possibility of desperately-needed preservation and restoration efforts.
From a distance, the mansion looks like an old castle perched on a hilltop, surrounded by mature trees. But up close, visitors can easily see the crumbling brick chimneys, decaying walls and broken windows.
The interior walls have been defaced with brightly-colored graffiti, and full sections of the ceiling are missing in some rooms, allowing light (and precipitation) from outdoors to come streaming into the home. A few small details, like the intricate brickwork of the fireplaces and the presence of an old piano, hint at the former grandeur of this long-neglected mansion.
Hell House Altar (Ellicott City)
Hidden in the dense brush of Patapsco Valley State Park, persistent explorers can find the only remaining evidence of St. Mary’s College, which once graced the property as a training ground for young men preparing to enter the priesthood: a decrepit stone gazebo containing a lonely metal cross.
The college was built in 1868 and remained in operation until 1972, when a diminishing student body and inadequate funds led to its closure and abandonment. The vacant campus buildings were a popular destination for urban explorers, vagrants and bored teenagers, many of whom left their marks on the property via broken windows and crass graffiti.
The spooky-looking empty buildings became the subject of rampant rumors of supernatural activity, which only intensified after a suspicious fire consumed most of the campus in 1997. The ill-fated property known to locals as “Hell House” drew even more curiosity-seekers, most of whom hoped to catch a glimpse of a ghost or witness the effects of paranormal energy. The appearance of guard dogs and police patrols did little to deter visitors from making pilgrimages to the site.
Eventually, the burned buildings were demolished, leaving only the gazebo and the altar it shelters, which has been spray-painted with ominous-looking black and white symbols and drawings. The strange site is accessible via a set of stairs located on the south side of the railroad bridge near the intersection of Illchester Road and River Road. Currently, it remains one of the most interesting abandoned places in Maryland for visitors and residents to explore.
Our Final Thoughts on Abandoned Places in Maryland
Those who are into urban exploration in the Maryland state area, and wanting to explore abandoned places in Maryland, should get comfortable with Maryland trespassing laws. Luckily, in the state of Maryland, the laws are easy to understand and are pretty cut and dry.
