Édifice Marie-Guyart, Brutalist skyscraper in Parliament Hill, Canada.
The Édifice Marie-Guyart is a 33-storey, 132 m brutalist concrete tower on Parliament Hill in Quebec City. Its facade is a dense grid of deeply recessed rectangular windows set in thick pale grey concrete frames, with a smooth vertical strip along one edge carrying a suspended window-washing platform. Completed in 1972, it is the tallest building in the city and in Canada east of Montreal.
Construction started in 1967 during Quebec's government expansion and was completed in 1972 under architect Édouard Fiset's design. The tower became part of a larger push to strengthen provincial administration through contemporary architecture.
The building was named in 1987 to honor Saint Marie of the Incarnation, a founder of the Ursuline order in New France. This choice connects the modern structure to the region's spiritual heritage.
The Observatoire de la Capitale occupies the building's top floor, reached by lift, and gives a 360-degree view from 221 metres, taking in the Citadelle, the Château Frontenac and the city's fortifications. The tower stands on Parliament Hill in the La Cité-Limoilou borough, in the heart of downtown Quebec City.
The tower's nickname, Complexe G, comes from the letter-based naming of the 1963 Parliament Hill plan; the first 1965 version foresaw four towers of 22 to 25 floors, two and a half times what was built. A 1971 fire on the 29th floor, started by a faulty salamander heater, burned for 17 hours and delayed construction by over three months.
