Castle Plaza is a shopping centre located in the Adelaide suburb of Edwardstown approximately 7 km from the CBD, along South Road.
It was expanded in the mid 1980s and the new development was opened in July 1987. Attending that day were a number of local personalities including John Platten. Providing the guard of honour were the 1st Ascot Park Scout Group.
It contains three major tenants (Target, Coles - 14 Aisles, Foodland Supermarkets) and the Castle Tavern (including gaming room) as well as 66 specialty stores, plus two free standing fast food outlets.
The centre is currently owned by the CFS Retail Property Trust. In July 2007 it was announced that CFS had purchased the Hills Industries site (7.78 hectares) directly opposite Castle Plaza for $25.3 million. There are plans for a further $80 million retail development on this site subject to approval by City of Marion Council.
