Constructed over many decades, they embrace a number of different styles. The provincial government have been unwilling to pay for structures as lavish as those of the private sector, and few of the provincial buildings are of much prominence. Two of the most distinct and well-known structures in downtown Toronto are the old and current city halls. The Old City Hall was built in 1899 and is a prominent example of the late Victorian Romanesque Revival style. Across the street is the starkly different new Toronto City Hall opened in 1965. This brashly modernist structure was designed by Finnish architect Viljo Revell. It fronts Nathan Phillips Square, which was also designed by Revell. Today, both buildings are considered symbols of the city. The 3D Toronto sign was installed in Nathan Phillips Square for the 2015 Pan American Games and the sign was later made permanent. The University of Toronto (U of T) has embraced dramatic design and monumentalism, and its prominent location at the centre of the city has given its structures a wide impact. Built up over almost two centuries, the university's buildings cover a wide range of styles. The Collegiate Gothic style was embraced for many of the earliest buildings, such as Hart House, Trinity College, and Burwash Hall, but there are also examples of almost all the Victorian revival styles on campus. In recent decades, the university has built examples of modernism, such as McLennan Physical Laboratories; brutalism, such as Robarts Library; and postmodernism, such as the graduate house by Pritzker Architecture Prize winner Thom Mayne. Sir Norman Foster designed the University of Toronto's Leslie L. Dan Pharmacy Building, which is home to the largest pharmacy faculty in Canada. It was completed in 2006. The other two major universities, York and Ryerson Universities, have largely been built in more recent years and have fewer architectural monuments. Ryerson was long mostly hidden within the downtown streetscape, with the Brutalist library, podium, and Jorgensen Hall complex being one half block east of Yonge Street, but since the 1990s, an unprecedented building project has greatly expanded the campus and made it much more visible. York, like many of the universities that largely came into being in the 1950s and 1960s, has mostly eschewed monumentalism in pursuit of less dramatic, but more egalitarian architecture, particularly Brutalist architecture, such as the Scott Library. The Ontario College of Art and Design, for many years confined to a series of comparatively unprepossessing buildings in the western part of downtown, was transformed in 2004 by the addition of the Will Alsop's Sharp Centre of Design.
