Opened in 1931, Marlboro Psychiatric Hospital was located on in the eastern part of the township. It was opened with much fanfare as a "state of the art" psychiatric facility. It was closed 67 years later on June 30, 1998, as part of a three-year deinstitutionalization plan in which some the state's largest facilities were being shut down, with Marlboro's 800 patients being shifted to smaller facilities and group homes. The land that the hospital was placed on was known as the "Big Woods Settlement". It was largely farm land but there was a large distillery on the property which was torn down to make room for the hospital. Additionally, due to the long residential stays at the hospital, a cemetery was also located near the hospital for the residents who died while in residence and were unclaimed. There is currently a large fence around the hospital and the hospital was completely demolished in 2015. Most of the land was handed over to the Monmouth County Park system and some of the ground will be the final linkage of the Henry Hudson Trail. The park system had developed the Big Brook Park and continues to expand and work on the park to provide services to the Monmouth County residents.
