Basilique Notre-Dame d'Arcachon, Minor basilica in Arcachon, France.

The Basilica of Notre-Dame in Arcachon is a Gothic Revival church built from red brick with Angoulême stone bands and window surrounds. It has a single 45-metre stone spire with pinnacles and a cross, a nave with pointed windows, a transept with a rose window, and a rounded apse. The older Sailors' Chapel opens directly into the nave.

The first stone of the new church was laid in 1856 beside the older Sailors' Chapel, and it opened for worship in 1859; the first services followed in 1861. The plans came from Gustave Alaux, and Michel Alaux extended the building to its present form by 1884. Pope Pius XII raised it to minor basilica on 9 March 1953.

The Sailors' Chapel within the building shows how locals and visitors today gather to pray for those at sea and maritime safety. The space conveys a living connection between the fishing community and their spiritual traditions in this port town.

The building sits about 200 meters from the beach and is easy to reach on foot. Visitors can attend services during the week and explore the interior spaces at their own pace.

The chapel's entrance now opens directly into the nave of the basilica: its original Baroque doorway, with columns supporting a tympanum, was dismantled to make this passage. The chapel roof burned on 6 January 1986, yet the alabaster Virgin and Child, 51 cm high and 23 cm wide, survived and was returned when the chapel reopened on 25 March 1987.
