Mont-Saint-Michel abbey transfer threatens CMN's solidarity model for 100+ monuments
On June 17, 2026, the office of the French Prime Minister revealed a governance reform aimed at consolidating the management of Mont-Saint-Michel, which will eliminate the existing dual oversight by the Établissement Public du Mont-Saint-Michel (EPMSM) and the Centre des Monuments Nationaux (CMN). This abbey, designated a UNESCO World Heritage site in 1979, drew more than 1.6 million visitors in 2025 and contributes between €6-7 million annually to the CMN. On June 18, 2026, unions CGT, CFDT, and SUD initiated a national strike, expressing concerns that the abbey's loss could jeopardize funding for over 100 monuments. Planned renovations are estimated at €88 million, with no definitive government compensation. Prime Minister Sébastien Lecornu cited the inefficiencies of dual management as a reason for the reform, while unions worry about increased fees and job insecurity.
