The Core Shopping Centre which consists of TD Square, the Holt Renfrew building, and the former Calgary Eaton Centre, is the dominant shopping complex located in the downtown core of Calgary, Alberta, Canada. It spans three city blocks and contains approximately 160 retailers on four levels. The property also contains four major office towers (TD Canada Trust Tower, Home Oil Tower, Dome Tower) and the historic Lancaster Building. It is the hub of downtown Calgary’s +15 skywalk system, and as such is the busiest shopping centre in the City by pedestrian count, with around 250,000 visitors passing through each week. The centre's architectural focal point is a vast suspended glass skylight which spans the length complex. As of October 29, 2010, The Core offers free evening and weekend parking at its underground lots.
The Core is bounded by 8th Avenue SW (Stephen Avenue pedestrian mall) on the south, 7th Avenue SW (LRT Corridor rapid transit line) on the north, and extends above 3rd Street SW (Barclay Parade) and 4th Street SW. The mall is directly connected to the neighbouring retail complexes of Bankers Hall (south) and Scotia Centre/Hudson’s Bay Store (east) via the +15 skywalk system. It also contains the Devonian Gardens, a unique 2.5acre glass-enclosed indoor botanical park, which reopened to the public on July 27, 2012 after a complete renovation.
