St. Elizabeths Hospital is a psychiatric hospital operated by the District of Columbia Department of Mental Health. It was the first large-scale, federally run psychiatric hospital in the United States. Housing several thousand patients at its peak, St. Elizabeths had a fully functioning medical-surgical unit and offered accredited internships and psychiatric residencies. It has since fallen into disrepair and the grounds are mostly abandoned, although the east campus is still operational and it opened a new facility in 2010.
