Megacity Montreal is the title of a chapter in a book titled Megastructure: Urban Futures of the Recent Past written by architecture theoretician Reyner Banham. Place Bonaventure in Montreal is featured as an example in this book.
Place Bonaventure was the world's largest building upon its completion in 1967. Place Bonaventure was first conceived as an exhibition hall, international trade centre, and hotel. The building covers an area of 2 ha (5 acres) and is built over 18 Canadian National Railway tracks leading to Central Station. Place Bonaventure is also linked to subway system and the Tour de la Bourse (Stock Exchange Tower) through a network of underground tunnels. Until major renovation work drastically changed its appearance, Place Bonaventure was an entirely self-contained cubic structure that had few windows. Construction began in 1964 and was completed in 1967.
Architectural critics visiting the world fair were struck by Montréal's Grain elevators which, with their networks of covered conveyors belts, irresistibly evoked the images megastructures touted in experimental circles.
