The Richardson Olmsted Campus 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 famed landscape team of Frederick Law Olmsted and Calvert Vaux in the late 1800s, incorporating a system of enlightened treatment for people with mental illness developed by Dr. 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. Today, the Richardson Olmsted Campus is being converted, beginning with the now open Hotel Henry Urban Resort Conference Center and 100 Acres: The Kitchens at Hotel Henry, both within the Towers Building and two flanking buildings (about one-third of the Campus). The Richardson Olmsted Campus will also house The Lipsey Architecture Center Buffalo. The remaining buildings have been stabilized pending future opportunities. History and architecture The large Medina red sandstone and brick hospital buildings were designed in 1870 in the Kirkbride Plan by architect Henry Hobson Richardson with grounds by landscape architect Frederick Law Olmsted. The campus consists of a central administrative tower and five pavilions or wards progressively set back on each side, for eleven buildings total, all connected by short curved two-story corridors. Patients were segregated by sex, males on the east side, females on the west. The wards housed patients until the mid-1970s. The central administration building was used for offices until 1994. The campus, the largest commission of Richardson's career, marks the advent of his characteristic Romanesque Revival style. When emulated by later architects, this style is referred to as Richardsonian Romanesque. It has been the subject of a long-term preservation campaign. Nevertheless, three pavilions on the east side were demolished in the 1970s to make way for newer psychiatric facilities. In 1927, the northern farmlands were transferred back to the State for the development of what is today Buffalo State College. In 1973, the Asylum was added to the National Register of Historic Places and in 1986, it was designated a National Historic Landmark. Patient records from 1881 to 1975 are in the collection of the New York State Archives in Albany, NY. Architectural plans and drawings are in the H.H. Richardson Collection in the Houghton Library at Harvard University. Preservation efforts The Preservation Coalition of Erie County (renamed
