Marion is a suburb located in the City of Marion in Adelaide around 10 km south-west from the CBD. Founded as a rural village in 1838 on the banks of the Sturt River, Marion was found to have rich soil and the population expanded rapidly. Colonel William Light laid out the plan for the village, as he had done with the City of Adelaide itself.[citation needed] Marion is bordered on the North by Oaklands Road, on the East by Marion Road, on the South by Sturt Road and on the West by a roughly straight line from Finniss Street in the south to The Parade.
