Soaring 617 feet, Place Ville Marie was Canada’s tallest when it opened in 1962. The cruciform skyscraper still has plenty to boast about. The five-building complex has 3.4 million square feet of space. PVM is the official head office for The Royal Bank of Canada, the country’s largest bank. This was the origin of The Underground City. The network has evolved into 1,600 stores, 20 miles of passenger tunnels and a web of metro stations serving a half million people each day. On the 46th floor is Observatoire Place Ville Marie. The glass observation deck provides stunning, 360° views of the city.
