The heart of Sydney, the central business district, is home to major shopping centres, hotels and entertainment venues, and many important financial and business institutions. Much of Sydney’s commercial history is reflected in the buildings – from imposing banks and historic structures, such as Victorian shopping arcades and the old GPO in Martin Place, to ultra modern high-rises. Some of Sydney’s oldest structures are here, such as the 1819 Hyde Park Barracks and 1822 St James Church. Indeed, the City Centre is a fascinating place to live, work, shop and visit.
