Richardson in 1870-1872 and built between 1872 and about 1890.","why_significant":"It is an early institutional work by Henry Hodson Richardson and shows the development of his style toward simplification and effective massing. Frederick Law Olmsted planned the hospital's location and grounds, adding importance to the history of landscape architecture. The form cites architectural historian Henry-Russell Hitchcock, who regards it as a key work in the formation of Richardson's mature style.","narrative":"Buffalo State Hospital, originally the Buffalo State Asylum, is a large hospital complex on Forest Avenue in Buffalo. Its administration building, with twin towers, steep hipped roofs and round corner turrets, dominates the northwest skyline. H.H. Richardson designed the complex between 1870 and 1872 on a flattened V-shaped plan, with wards radiating from a central unit. The central building is rough-faced brown sandstone, while most outer wards are brick, substituted for stone to save money. Frederick Law Olmsted located the buildings and planned the grounds, and A.J. Warner supervised construction. Patients arrived in 1880, the formal opening came in 1881, and all buildings were finished around 1890. The three easternmost wards were demolished in the 1960s, leaving twelve Richardson buildings. The complex matters as an early example of Richardson's move toward simplified, massive composition, and for its Olmsted landscape connection. Its continued use was uncertain when it was listed.","period_of_significance":"1871-1890","architect_builder":"Henry Hodson (H.H.) Richardson, architect; A.J.
