Dunedin is the second-largest city of New Zealand's South Island. It is the main city of Otago Region. However, Dunedin is one of the four major cities of New Zealand because of its cultural, historic and geographic richness. Urban area of Dunedin spreads over the central-eastern coast of Otago and surrounding the area along head of Otago Harbour. Otago Harbour and hills surrounding Dunedin show history of an extinct volcano. Dunedin city suburbs extend out towards the surrounding hills and valleys, onto the headland of the Otago Peninsula, then reaching and along the sea sides of the Otago Harbor as well as the Pacific Ocean.Dunedin is famous for its higher education systems and world known University of Otago is part of this city, established back in 1869 and the multidiscipline Otago Polytechnic. Dunedin accounts for a rich history in the arts. To make art to be freely available for everybody to enjoy, surprisingly the city is heading towards embracing street art where there are several blank walls currently transformed into artwork done by international and local artists.
