Christchurch is the largest city in the South Island of New Zealand and the seat of the Canterbury Region. The Christchurch urban area lies on the South Island's east coast, just north of Banks Peninsula. It is home to residents, making it New Zealand's third most-populous city behind Auckland and Wellington.The Avon River flows through the centre of the city, with an urban park located along its banks. At the request of the Deans brothers—whose farm was the earliest settlement in the area—the river was named after the River Avon in Scotland, which rises in the Ayrshire hills near to where their grandfather's farm was located.Archaeological evidence has indicated that the Christchurch area was first settled by humans about 1250. Christchurch became a city by Royal Charter on 31 July 1856, making it officially the oldest established city in New Zealand. The Canterbury Association, which settled the Canterbury Plains, named the city after Christ Church, Oxford. The new settlement was laid out in a grid pattern centred on Cathedral Square; during the 19th century there were few barriers to the rapid growth of the urban area, except for the Pacific to the east and the Port Hills to the south.
