On a wet day in Adelaide, September 5, 2013 Australia. You can see St Peter's Cathedral!

Adelaide is the capital city of South Australia and the fifth-largest city in Australia. The demonym "Adelaidean" is used in reference to the city and its residents. Adelaide is north of the Fleurieu Peninsula, on the Adelaide Plains between the Gulf St Vincent and the low-lying Mount Lofty Ranges which surround the city. Adelaide stretches 20 km (12 mi) from the coast to the foothills, and 90 km (56 mi) from Gawler at its northern extent to Sellicks Beach in the south.

Named in honour of Adelaide of Saxe-Meiningen, queen consort to King William IV, the city was founded in 1836 as the planned capital for a freely settled British province in Australia. Colonel William Light, one of Adelaide's founding fathers, designed the city and chose its location close to the River Torrens in the area originally inhabited by the Kaurna people. Light's design set out Adelaide in a grid layout, interspaced by wide boulevards and large public squares, and entirely surrounded by parkland. Early Adelaide was shaped by religious freedom and a commitment to political progressivism and civil liberties, which led to the moniker "City of Churches".

Prior to its proclamation as a British settlement in 1836, the area around Adelaide was inhabited by the indigenous Kaurna Aboriginal nation (pronounced "Garner" or "Gowna").
