The Swan River Colony was the name given to the British penal colony established on the Swan River by Captain James Stirling in 1829. The colonists first sighted land on 1 June, the official Proclamation was made on 18 June, and the foundation of the colony took place on 12 August. The two separate townsites of the colony developed slowly into the port city of Fremantle and the Western Australian capital city Perth.
