Standing 1,815ft (553m) high, Toronoto's landmark CN Tower is the world's tallest building, a celebrated icon, an important telecommunications hub and the centre of tourism in Toronto. About two million people visit the tower each year to take in the panoramic view and enjoy all its attractions. The tower was built in 1976 by the company Canadian National, who undertook the project simply to prove the strength of Canadian industry and solve the city's communication problems. Since then tourist attractions and facilities have been added, and the revitalised tower opened to the public in 1998, proving a hit with locals and visitors alike. The tower has four look out levels. At the first at 1,122ft (342m) is an outdoor observation deck with a spectacular glass floor; somewhat higher at the next level is an indoor observation deck and the Horizon's café, offering light meals high in the sky; at the 1,150ft (351m) level is a revolving restaurant, which rotates once every 72 minutes, allowing a stunning view of the city below while dining on the award-winning fare; finally comes the top level, at a dizzying 1,465ft (447m), known as the Sky Pod. At the top of the CN Tower visitors stand on the world's highest public observation deck. The tower is situated in the heart of Toronto's entertainment district, on the north shore of Lake Ontario.
