The name "Place Ville-Marie" is often used to refer to the cruciform building only, but it also applies to four shorter office buildings which were built around it in 1963 and 1964, and to the urban plaza which lies on top of the largest section of the shopping promenade, and between the buildings. From a postal point of view the cruciform tower is "1, Place Ville-Marie" and the lesser buildings around it are "2, Place Ville-Marie" and so on. The buildings and the plaza have been given many facelifts over the years. In the latest facelift, much of the grey concrete and terrazzo of the plaza was covered with grass, flowers and shrubs. The complex has 2,700,000 square feet (250,838 m2) of space and parking for about 900 cars. There are about 70 tenants with 3,000 employees. Via Rail has its headquarters in "3, Place Ville-Marie". Place Ville-Marie was one of the first designs of Henry N. Cobb and I. M. Pei, who was later to become a famous master of Modernist architecture. His design was controversial from the start given its proximity to many Montreal landmarks and the vast changes it would bring to the downtown core. According to design historian Mark Pimlott, "The most radical aspect of the Place Ville Marie project was that nearly one-half of its 280,000 square metres area were beneath street level... deriving the obvious benefit of being protected from Montréal’s extreme winter and summer climate." Its vast network and multi-purpose is juxtaposed with a continuous interior "with episodes of civic gravity and monumentality". At the time of construction, the main tower was known as the tallest skyscraper in the Commonwealth, and was the third tallest skyskraper on earth outside the United States. The equivalent of three floors was added late in the project to ensure that this building would not be topped by the neighboring Tour CIBC which was built at the same time. Conceived and built at a time when Montreal was the Metropolis of Canada during the 1960s, the structure's largest occupant and anchor tenant was the Head Office of the Royal Bank of Canada, the country's largest bank. The central plaza became an important new public space in downtown Montreal, hosting an historic election rally for Pierre Elliott Trudeau during the 1968 federal election. Developer William Zeckendorf lost a bet to then Royal Bank President Earle McLaughlin, making payment in full (US$0.10) in an elaborate dime encased in acrylic. Exactly what the bet concerned is unknown. Though the Head Office was moved to Toronto in the 1970s, RBC still maintains the regional headquarters there. In 1975 Air Canada's headquarters were at 1 Place Ville-Marie. Mayor Jean Drapeau chose the name himself. Ville-Marie was the name of the Catholic colony founded at what is now Montreal in 1642.
