Trentemoult

Maison des Isles

In the heart of the village, on allée Claude-Choëmet, the Maison des Isles is the neighbourhood’s community hall.

It hosts the book fair (La Longue Vue), charity exhibitions and the Duo festival’s welcome desk.
It is also home to the Trentemoult Choir’s rehearsals (Wednesday evenings), Jeudivers board games (Thursday afternoons) and councillors’ drop-in sessions.

Getting involved

Your neighbourhood councillor (Trentemoult-Les Isles): Morgane Le Floch holds a drop-in one Saturday morning a month at the Maison des Isles. Call 02 40 84 43 64 to book.
Citizens' forums: meetings with councillors, with more time for discussion.
Neighbourhood budgets: the participatory budget that produced the "Moult'Pattes" dog park in parc de la Grève (opened May 2026).
