The Providence Preservation Society was formed in 1956 to respond to the proposed demolition of a number of 18th- and early 19th-century houses on College Hill. The Providence Preservation Society (PPS) has grown from that small neighborhood group to a multi-faceted citywide preservation organization. With a membership of over 1,000 households, a professional staff, and countless volunteers, PPS is able to provide a broad range of services that fulfill its mission to improve the quality of life in the city of Providence through historic preservation and the enhancement of the built environment.
