Osmanli Mosque, Turkish mosque in Bellevue-Chantenay district, Nantes, France

The Osmanli Mosque is a prayer house in Nantes with a large prayer hall featuring white limestone facades and concrete surfaces. The complex includes classrooms, a Turkish cafe, a grocery store, and a library alongside the main prayer space.

Construction of the mosque began in 2005 following approval from then-mayor Jean-Marc Ayrault and was completed in 2010. It emerged from the needs of the growing Turkish population in the city for a place to gather for religious and community purposes.

The mosque serves as a central gathering place for the Turkish community in Nantes and displays architectural elements rooted in Seljuk and Ottoman traditions. Visitors can observe geometric patterns carved into the stone decorations that define the interior spaces.

The mosque stands at 21 bis boulevard du Bâtonnier-Cholet in the Bellevue-Chantenay-Sainte-Anne district, among warehouses and factories; from the Cheviré bridge only the minaret shows between the sheds. A planted strip separates the boulevard from the cultural centre, so the approach on foot is direct. The prayer hall is entered by two doors, one at ground level and one at the mezzanine.

The minaret is built of stone around a metal frame, modelled on Ottoman minarets such as that of the Süleymaniye Mosque in Istanbul, built by Mimar Sinan between 1550 and 1557. The single grey copper-clad dome covers one square prayer hall, as at the Yeşil Mosque of Iznik (1378–1391).
