In the late 1800s and well into the 1900s there were several psychiatric hospitals around New York State with a notable one opening in the Hudson Valley. Over those years people would check in to these facilities, willingly and sometimes unwillingly, for treatment for a variety of conditions. Depression, schizophrenia and even homosexuality could have an individual admitted and some never left.

One of the most iconic psychiatric hospitals in New York State was a mammoth structure sitting on nearly 300 acres in Poughkeepsie called the Hudson River State Hospital. Abandoned since 2003, much of the campus has been dismantled. Let's take you inside before the demolition.
