Covering a total of over 200 hectares (490 acres), it extends around three sides of the city's centre at a distance from it of some 1-3 km (1-2 mi) in a broad 7 km (4 mi) crescent from the Oval at Kensington in the south through the suburbs of Mornington, City Rise, Belleknowes, Roslyn, Maori Hill, Prospect Park, Glenleith, Woodhaugh, The Gardens and Dunedin North and the slopes of Signal Hill. The fourth side of the central city is bounded by the Otago Harbour.
