Toronto has undergone significant architectural changes from mid-1900s to present day, with old buildings being replaced by modern skyscrapers along major streets like Front and Yonge. Nathan Phillips Square currently houses the annual skating rink installation, while Bay Street is dominated by glass, marble and steel high-rises that make up the financial district. Two iconic landmarks, Eaton Centre and City Hall, were both designed in the 1970s and shaped shopping and civic design in North America. Old City Hall, dating back to the late 1800s, remains standing next to the current larger City Hall building.
