In 1965, the 47-story and 623ft/190m Place Victoria in Montreal’s financial district, also known as the Stock Exchange Tower or Tour de la Bourse, surpassed Chicago’s 1000 Lake Shore Plaza as the world’s tallest concrete skyscraper. Designed and built from 1960-1965 by Italian architect Luigi Moretti and Italian structural engineer Pier Luigi Nervi, along with a team of professionals based in both Montreal and in Italy, the project brought together expertise from both sides of the Atlantic. In her talk, based on research for her dissertation, Katie Filek will detail the use of concrete in the tower and discuss how the project was the product of highly localized conditions of costs, materials, and labour in Montreal that relied on the specialized knowledge of Montreal-based architects and engineers for its realization.
