Glenn Dale Hospital is known for rumors of being haunted by the Goat Man of Maryland after its closure in 1982, as well as other paranormal activity stemming from its past as a tuberculosis sanatorium. The large, abandoned campus, which features 23 buildings and underground tunnels, is a popular site for ghost hunters and urban explorers. The facility was built in the 1930s as a tuberculosis sanatorium and isolation hospital. It closed in 1981 or 1982 due to high levels of asbestos and the need for structural upkeep, leading to its abandonment. The grounds are rumored to be haunted by the Goat Man, a mythical creature described as half-man and half-goat. The abandoned hospital attracts paranormal investigators and ghost hunters drawn to its history and eerie atmosphere. The site consists of 23 buildings spread across 216 acres. Entering the property is illegal and can result in citations for criminal trespassing, as police regularly patrol the grounds.
