6. Edgewood State Hospital, Long Island
Edgewood State Hospital was located in Deer Park, Long Island functioning as both a psychiatric facility and tuberculosis hospital. It’s notable for being a treatment location for traumatized soldiers, operated by the U.S. War Department after the beginning of WWII. Mason General Hospital, as it was referred to, also included a few buildings at Pilgrim State. A government sponsored documentary Let There Be Light was filmed there but eventually banned by the government in fear that it would be damaging to troop morale. The film was finally released in the 1980s, screened at the Cannes Film Festival in 1981, and selected for film preservation by the Library of Congress in 2010. You can view it on Amazon.
The large imposing main building was constantly on fire, making it a popular urban exploration spot for youth in the 1970s and 80s. An old, grainy video from 1986 shows what was left before its demolition in 1989, allegedly the largest demolition of state-owned ever.
Today, the site is managed as an oak-brush plains preserve managed by the New York State Department of Environmental Conservation, but with a land access permit you can explore the remnants which include rail tracks, lampposts, fire hydrants and the like.
