Place Ville Marie (PVM for short) is a large office and shopping complex skyscraper in Downtown Montreal, Quebec, Canada, comprising four office buildings and an underground shopping plaza. It serves as the main and official headquarters for Royal Bank of Canada, Canada's Largest Bank. The main building, 1 Place Ville Marie (formerly Royal Bank Tower from its anchor tenant), was built in the International style in 1962 as the headquarters for the Royal Bank of Canada, which it still is presently. It is a , 47-storey, cruciform office tower. The complex is a nexus for Montreal's Underground City, the world's busiest, with indoor access to over 1,600 businesses, numerous subway stations, a suburban transportation terminal, and tunnels extending throughout downtown. A counter-clockwise rotating beacon on the rooftop lights up at night, illuminating the surrounding sky with up to four white horizontal beams that can be seen as far as away. This beacon is not considered as a NAVAID for aviation purposes. Buildings 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 of space and parking for about 900 vehicles. There are about 70 tenants with 3,000 employees. Via Rail has its headquarters in "3, Place Ville Marie". Site The location of Place Ville Marie was originally a vast railway trench gouged in the flank of Mount Royal between the southern portal of Canadian National Railway's Mount Royal Tunnel and Central Station. Most of the building was thus built over the tracks, requiring the structure to be more resistant to vibrations than normally required. As a result, it is the most earthquake-resistant office tower in Montreal. All of the land bounded by Cathcart Street, Dorchester Boulevard (now René Lévesque Boulevard), University Street (now Robert-Bourrassa Street) and Mansfield Street was owned by
