Royal Bank Plaza

Royal Bank Plaza is a skyscraper in Toronto, Ontario, Canada that serves as the de facto operational headquarters of the Royal Bank of Canada.  Built to be the new main office of the Royal Bank after its decision to move its centre of operations from Place Ville Marie in Montreal to Toronto in the late 1970s, Royal Bank Plaza consists of a South Tower and a North Tower. The exteriors of the structures are largely covered with gold-bronze glass with tan granite accents. Together, both towers contain more than 14,000 windows which project from the facade to form angular bays set into brushed aluminum frames. The glass for the body of the building was manufactured by Canadian Pittsburgh Industries and was coloured using 2,500 oz (71,000 g) of gold, valued at CA$70 per pane at the time of installation.
