You thought the works on the Paris metro were wrapping up after this summer? Bad news: you’ll need to rethink your travel habits this autumn if you pass through the Quartier Latin. As part of the network modernization projects, RATP is launching a major renovation program at the Saint-Michel station. The result: from September 14 to December 19, 2026 inclusive, the stop will simply not be served on the Line 4, and trains will pass through without stopping there.
This lengthy project, spanning almost four months, aims to refresh the facilities and improve passenger comfort at this aging hub of the capital’s key line. However, for daily commuters and visitors alike, the closure of this nerve center is likely to complicate trips a bit over the entire quarter.
Fortunately, central Paris remains easily reachable on foot from neighboring stations. To reach the Saint-Michel fountain area or the 'Île de la Cité, you’ll need to plan ahead and use the nearby Cité (Line 4) or the Odéon stop (Lines 4 and 10). Only the metro station is affected; RER B and C services at Saint-Michel - Notre-Dame should remain operational based on current information.
Just plan a little extra time for your daily journeys!
