Église Notre-Dame-de-l'Assomption de Gruissan, Medieval church in Gruissan, France.

Église Notre-Dame-de-l'Assomption de Gruissan has a nave of four bays with stone side walls and two levels of wooden balconies. Massive pointed diaphragm arches cross beneath an exposed wooden beam ceiling, and the choir and side chapel are rib-vaulted. The bell tower is a former watchtower of the fortified village.

The church was founded in the 13th century and still displays defensive features from its original construction including narrow openings. These were later enlarged to allow greater light into the interior.

The church is deeply connected to the fishing community of Gruissan and houses a painting by Jacques Gamelin from 1797 commemorating thirty-two local fishermen who drowned at sea. This work tells the story of the dangerous maritime labor and remains an important memorial for the community.

Visitors can explore the interior during opening hours to view the architecture and artistic details throughout. It is advisable to check ahead for accessibility hours as times may vary throughout the week.

The baldachin over the main altar rests on six columns of pink marble from Caunes-Minervois, so tall that the vaults were raised in 1787 to fit them. The retable was given by Arthur Richard Dillon, lord of Gruissan and last Archbishop of Narbonne, then reworked after the Revolution with a polychrome wooden statue of the Assumption of Mary.
