1250 René-Lévesque, formerly known as the "IBM-Marathon Tower," is Montreal, Canada's second-tallest skyscraper, with a roof height of 199 meters (without its spire), and a total height of 226.5 meters including the spire.[4] The height definition follows the city’s National Building Code, which excludes decorative spires, whereas the international Council on Tall Buildings and Urban Habitat (CTBUH) includes it, making it Montreal’s tallest building.[5]
This 47-story skyscraper was designed by Kohn Pedersen Fox Associates and completed in 1992. It was constructed between 1988 and 1992 as a project led by IBM and Marathon Realty with an investment of $250 million to consolidate IBM’s operations in Montreal, relocating 1,000 employees from Place Ville Marie.[6]
The building’s location in downtown Montreal serves as a visual boundary between the commercial center and the historically residential west side, a concept inspired by KPF’s Westend Tower in Frankfurt, Germany.[7] It is located next to Bell Centre and Windsor Station
