10. Rockland Psychiatric Center, Orangeburg, New York

Rockland Psychiatric Center abandoned hospital

The Rockland Psychiatric Center opened in 1931 in Orangeburg, New York, and is one of the only locations on this list that is still partially being used as it was initially intended. But like many psychiatric centers in the 20th century, the facility began to decline as it turned to more controversial treatment methods.

Today, Rockland Psychiatric Center still operates in a portion of the complex’s newer buildings, while its older structures remain abandoned and continue to age. The inhabited portion holds approximately 400 beds and is home to patients with psychiatric illnesses. The facility has become a pop culture celebrity because some of the buildings have been used as a primary shooting location for the Netflix television show Orange is the New Black and it was the setting of the second season of Ryan Murphy’s American Horror Story: Asylum.
