1857, the building was refurbished and enlarged again, according to a design by the firm Cumberland and Storm, to accommodate courts with the original 1829 building becoming the east wing. From 1880 to 1891, the building was again expanded twice in order to accommodate its law school. The building was designated a National Historic Site of Canada in 1979, and by the City of Toronto under the Ontario Heritage Act in 1990. Design Despite the expansions, the hall presents a unified design in the late Palladian style. The iron fence surrounding the lawns of Osgoode Hall has become a landmark in itself. Its distinctive iron gates are narrow and restrictive; it is a long-standing myth that they were designed to keep livestock out of the grounds of the hall. Despite this, an incident in the 1950s occurred in which students unsuccessfully attempted to pass a cow through one of the gates. The gates were likely due to Victorian architectural fashion, rather than wandering cattle. Two libraries are housed within Osgoode Hall: the Great Library of the Law Society of Ontario and a smaller library for judges. The Great Library was designed by Cumberland and Storm (1857–1860) and features an ornate plaster ceiling, cork floors, an iron spiral staircase and etched glass windows. A War Memorial by Frances Loring (1887–1968), sculpted in 1928, was added to the Great Library in honour of Ontario lawyers and law students who were killed during the First World War. Behind the Great Library (and accessible through it) is the American Room, designed by Burke and Horwood in 1895, a more intimate room with a spiral staircase. The Toronto Courthouse at 361 University Avenue, directly to the north, is accessible through a connecting tunnel.
