The Tour Montparnasse, currently the tallest building in Paris, will be fully vacated and closed to the public on 31 March, marking a decisive step toward its long-planned renovation and transformation. The announcement was made at a meeting held at Paris City Hall, where Frédéric Lemos, representing one of the building’s co-owners, confirmed that preparatory measures are now formally underway.
According to Lemos, the tower’s co-owners voted by an overwhelming 99.5 percent on 19 December 2025 to proceed with the closure, following recommendations from the Île-de-France Prefecture and the Paris Prefecture to accelerate the renovation process. In a joint letter dated 14 November 2025, the authorities had urged the rapid closure of the building to the public, citing safety concerns, including the presence of asbestos, and calling for action no later than early 2026.
Renovation work is expected to begin after the summer of 2026, following the signing of a protocol with the City to advance the restructuring of the adjacent Maine Montparnasse shopping center. The redevelopment will see the 209-meter-high building comprehensively reimagined as a mixed-use structure, incorporating a hotel, retail spaces, and services, and crowned by an agricultural greenhouse. The project is estimated to exceed €600 million and is anticipated to take approximately four years to complete.
These steps signal the most significant shift for Tour Montparnasse since its completion in 1973, setting the stage for a transformation intended to reposition one of Paris’s most debated high-rise buildings within the city’s contemporary urban fabric.
