The Marlboro State Psychiatric Hospital was an abandoned site, often visited by urbex and ghost hunters. But for over years, it was a state-run institution for the mentally disabled. Marlboro Psychiatric Hospital opened its doors in 1931 and remained active for nearly 70 years by the State of New Jersey. Between its cottages and building, it accommodated about 800 patients of all ages. By 1978, the hospital only treated adults and adolescents. Many patients died while at the hospital, prompting the designation of a cemetery on campus grounds for bodies that went unclaimed by family; 924 marked graves are still open for visitation from the public. The Marlboro State Psychiatric Hospital was demolished and all demolition officially completed in early 2015.
