Paris’s Montparnasse Tower is going to close because the building needs much more than a simple repair. The observatory at the top will close to the public on March 31, 2026, and the tower will then be emptied for a large renovation project. The official site says this work will completely transform both the tower and its surroundings, so visitors are now seeing the last weeks of the old Montparnasse experience. (tourmontparnasse56.com)
The biggest reason is that the tower is old and outdated. Built in the 1970s, it still contains asbestos, and French authorities pushed for a faster closure because of safety concerns. The owners then voted to vacate the building. Paris officials also say the larger Maine-Montparnasse complex suffers from technical and energy problems, and that its old, car-focused design no longer matches today’s needs for mobility, climate action, and public health. In short, the site no longer works well for a modern city. (lemonde.fr)
There is also an image problem. For years, many people in Paris have disliked the tower’s dark, heavy look. The new design by Nouvelle AOM aims to make it lighter, clearer, and greener. The dark glass will be replaced with a more transparent facade, and the project includes natural ventilation and other environmental systems. According to the engineering team, the renovated tower aims to reduce energy use by 90 percent compared with the original building. (lemonde.fr)
The renovation is not only about the tower itself. The city and the owners want to open the whole area to pedestrians and give it new life, with greener public spaces, more transparent ground floors, sports and cultural spaces, student housing, and a central square. The tower is also planned to include offices, a hotel, shops, a restaurant, and even an agricultural greenhouse at the top. A project presentation from 2025 said the main work on the empty tower was expected to begin in the second half of 2026 and last about 42 months. So the big renovation is happening because Montparnasse is being remade for a new century, not just cleaned up. (presse.paris.fr)
