 The oldest parts of the city are located in the flat areas south of the harbour; the North Shore was slower to develop because of its hilly topography, and was mostly a quiet backwater until the Sydney Harbour Bridge was opened in 1932, linking it to the rest of the city, with the suburbs surrounding the northern entrance to said bridge effectively developing North Sydney into a second central business district.The Eastern Suburbs sit on the coast of Sydney.They contain iconic beaches such as Bondi Beach and Coogee beach, and feature prominent seaside cliffs.
