The Octagon is the city centre of Dunedin in the South Island of New Zealand. It is an eight-sided plaza with a circular one-way carriageway, bisected by the city's main street, and is also the central terminus of two other main thoroughfares. The Octagon is predominantly a pedestrian reserve, with grass and paved features, and is surmounted by a statue of the Scottish poet Robert Burns. Several of Dunedin's significant buildings and institutions adjoin the plaza, which is also a major hub for public transport in Dunedin.
First laid out in 1846, the site was largely derelict for many years until the two major early parts of the city's settlement (to the north and south of the Octagon) were linked by the excavation of Bell Hill. From the 1890's on it rose to prominence as the city's central area. The Octagon was substantially renovated during the 1980's, and is now a centre of the city's cafe culture with many al fresco dining areas. New Year's Eve celebrations are held annually in The Octagon.
