Tour Maine-Montparnasse, also commonly named Tour Montparnasse, is a 210-metre office skyscraper located in the Montparnasse area of Paris, France. Constructed from 1969 to 1973, it was the tallest skyscraper in France until 2011, when it was surpassed by the 231-metre Tour First in the La Défense business district west of Paris's city limits. It remains the tallest building in Paris proper and the third tallest in France, behind Tour First and Tour Hekla.
