St Georges Terrace is the main street in the city of Perth, Western Australia. It runs parallel to the Swan River and forms the major arterial road through the central business district. Due to the coincidence between its west-east direction with the prevailing westerlies in Perth weather, it can develop into a successful wind tunnel.
Its western end is marked by the Barracks Arch, whereas the eastern end joins Adelaide Terrace at intersection with Victoria Avenue.
St Georges Terrace was named for St George's Cathedral. Originally, houses occupied by clergy of the cathedral and lay clerks of the cathedral choir constituted a substantial portion of the Terrace. Some of these houses such as The Deanery remain, however the majority of these were demolished in the 1960s.
The main streetscape between Barrack Street and William Street in the 1930s and 1940's constituted considerable uniformity of design and building height, by the late 1970s removal of significant older buildings for taller more modern buildings changed this irrevocably.
Set into the footpath along the street are 150 bronze tablets commemorating notable figures in Western Australia's history. These were installed in 1979, as part of the WAY 1979 celebrations, marking the state's 150th, or sesquicentennial year of European settlement.
