The Mississauga Civic Centre is the seat of local government of Mississauga, Ontario, Canada. The 37,280 square metre complex is a prominent example of postmodern architecture in Canada, finished in 1987 by Jones and Kirkland. It stands at 92 metres or 302 feet. The design was influenced by farmsteads which once occupied much of Mississauga as well as historical features of city centres. The building, for instance, includes a prominent clock tower. It was chosen as the winner of a design competition that included 246 submissions. Mississauga Civic Centre is located in the City Centre near Square One Shopping Centre and is home to the Mississauga City Council. The civic center building is considered one of the most iconic and recognizable buildings and cultural icons of Mississauga city.
