Paris, December 23, 2025 – After years of anticipation, the Montparnasse Tower is set to begin its extensive renovation phase in 2026, with a definitive closure date announced for March 31, 2026. This colossal project aims to transform the iconic skyscraper into a modern complex, featuring a luxury hotel and an agricultural greenhouse, while also addressing its original construction issues, including asbestos.
Official Closure and Renovation Details
The decision to close the tower was officially agreed upon by the co-owners, as reported by Le Figaro. From March 31, 2026, visitors will no longer be able to access the summit or the interior of the tower. The renovation is not only focused on modernization but also on rectifying existing issues. Constructed in the 1970s, the Montparnasse Tower, like many buildings of its era, was affected by asbestos, a key factor driving the need for this comprehensive overhaul.
Impact on Occupants and Future Plans
Numerous businesses currently operating within the tower will need to vacate their premises by the end of March 2026 to allow the renovation work to commence. The project is expected to drastically change the tower’s often-criticized appearance. Plans include an increase in height by nearly 12 meters and the installation of a clear glass facade. While the exact completion date remains unknown, the renovation is projected to last at least five years.
Adjacent to the Montparnasse Tower, the CIT tower and its commercial center will also undergo restructuring. This broader development will incorporate a vegetated square, new buildings, offices, shops, student housing, and leisure activities on green rooftops, with completion anticipated by 2032. This comprehensive restructuring aims to revitalize a significant district of the capital.
The Montparnasse District’s Transformation
The renovation of the Montparnasse Tower is part of a larger plan to rejuvenate the Montparnasse district, located at the crossroads of the 14th, 15th, and 6th arrondissements. Often described as being in a ‘concrete lethargy,’ the area is poised for a major transformation. The demolition phase of the tower’s interior is scheduled for mid-2026, marking a significant step in its rebirth.
Practical Information and Accessibility
The Montparnasse Tower is located at 33 Avenue du Maine, 75015 Paris 15. The renovation project will undoubtedly impact local traffic and public transport in the area. Further details regarding accessibility and specific project timelines will be released as the work progresses.
Broader Context: Paris’s Ongoing Developments
This renovation project is one of several significant developments underway or planned for Paris. Other notable changes include the suspension of the MaPrimeRénov’ energy renovation scheme from January 1, 2026, due to budget constraints, and a confirmed increase in the Navigo Pass price, which will exceed 90 euros monthly from January 1, 2026. These changes reflect a dynamic period of urban development and policy adjustments across the French capital and the Île-de-France region.
The city is also preparing for the festive season, with the Champs-Élysées Christmas illuminations set to begin and a cold wave bringing glacial temperatures for Christmas 2025. Meanwhile, the Eiffel Tower has extended its opening hours for the holiday period.
The transformation of the Montparnasse Tower represents a significant investment in the future of Paris, aiming to create a more modern, sustainable, and appealing urban landscape.
