Adelaide is the capital of South Australia, the largest city in the state and the fifth most populous city in Australia. "Adelaide" may refer to Greater Adelaide (including the Adelaide Hills) or Adelaide City Centre. The demon name Adelaide is used to refer to the city and its people. The traditional owners of the Adelaide area are the Kaurna people. The downtown area and surrounding parks are known as Tarndanya in the Kaurna language. Adelaide is located on the Adelaide Plains north of the Fleurieu Peninsula, between Saint Vincent's Bay to the west and the Lofty Mountains to the east. Its conurbation extends 20 km (12 mi) from the coast to the Lofty Mountains' foothills and 96 km (60 mi) from Gawler north to Sellicks Beach south. Named after Queen Adelaide, the city was established in 1836 as the intended capital of the only freely settled British province in Australia. Colonel William Light, one of Adelaide's founders, designed the city centre and chose a location near the River Torrens. Light's design, now a national heritage site, organized the city centre in a grid layout known as "Vision of Light", interspersed with wide boulevards and large public squares and Completely surrounded by parks. The first colonial Adelaide was shaped by the diversity and wealth of free settlers, unlike the criminal history of other Australian cities. Until the post-war period, it was Australia's third most populous city. It has been known for its leading examples of religious freedom and progressive political reform and is known as the "City of Churches" due to its diversity of beliefs. Today, Adelaide is known for its many festivals and sporting events, food and wine, coastline and hills, and effective defence and manufacturing areas. Adelaide's quality of life has consistently been ranked by various criteria throughout the 21st century, at one point being named Australia's most liveable city. As the government and commercial hub of South Australia, Adelaide is home to many government and financial agencies. Most of them are concentrated downtown along the cultural boulevards of North Terrace and King William Street.
