Bagnols-sur-Cèze (; 'Bagnols-on-Cèze'; ) is a commune in the Gard department in the Occitania region in Southern France.
A small regional centre, Bagnols-sur-Cèze was quite certainly a Roman town (the name of the town comes from the Latin meaning "related to baths, bathing-place") before the main part was built in the 13th century around a central arcaded square that is still preserved today. At the same period, the regional market was installed here, undoubtedly contributing to its expansion.
Bagnols-sur-Ceze expanded steadily after the Marcoule nuclear centre was established in 1956.
The old center of Bagnols-sur-Cèze retains its historic feel, with small streets and largely preserved architecture. Several façades are remarkable. The towns contains a notable museum of contemporary art, the Musée Albert-André, founded in 1868 as well as an archaeological museum with a collection of artifacts found mainly in nearby Roman sites.
The shoegaze music band named Alcest is from this city.
There are several murals featuring optical illusions.
Bagnols-sur-Cèze is twinned with:
Albert André, art collector of late 19th century art, who bequeathed his magnificent collection to the town of Bagnols-sur-Cèze, where it resides in the Mairie, as the Musée Albert André
