Dome

The atrium, close side view where structural system meets the outer wall; The BCE complex (now Brookfield Place) complex contains 242,000 square metres (2,604,866 sq ft) of office space in a 5 1/2 acre site, and consists of two towers, the Bay Wellington Tower and the TD Canada Trust Tower, linked by the six-storey Allen Lambert Galleria. Brookfield Place is also the home of the Hockey Hall of Fame. The Allen Lambert Galleria, sometimes described as the "crystal cathedral of commerce", was the result of an international competition and was incorporated into the development in order to satisfy the City of Toronto's public art requirements. Designed by Spanish architect Santiago Calatrava, it is one of the most photographed spaces in Toronto's financial district. The interior illustrates Calatrava's signature organic style, with a vaulted ceiling that is intended to evoke an avenue of trees. The Galleria also houses Toronto's oldest surviving stone building, the former Commercial Bank of Midland (built 1845). Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 12/27/2007)
