Sheffield City Centre (referred to locally as simply Town) is a district of the City of Sheffield and is covered partly by the City ward of the City of Sheffield. It includes the area that is within a radius of roughly 0.75 miles (1.2 km) of Sheffield Cathedral and is encircled by the Inner Ring Road, a circular route started in the late 1960s and completed in 2007. As well as the cathedral, buildings in the city centre include the Grade I listed Town Hall, the City Hall and the Winter Gardens. Several areas of the city centre have been designated as quarters. It is home to the city's major business, transport, leisure and cultural attractions.
