Buffalo State Hospital

The Richardson Olmsted Complex in Buffalo, New York, United States, was designated a National Historic Landmark in 1986. The site was designed by the American architect Henry Hobson Richardson in concert with the landscape team of Frederick Law Olmsted, landscape architect of New York City's Central Park, and Calvert Vaux in the late 1800s, incorporating a system of treatment for people with mental illness developed by Thomas Story Kirkbride. Over the years, as mental health treatment changed and resources were diverted, the buildings and grounds began a slow deterioration. In 2006, the Richardson Center Corporation was formed to restore the buildings. The building was renovated and opened in 2023 at The Richardson Hotel.
