Église Notre-Dame d'Aix-les-Bains, Romano-Byzantine church in Aix-les-Bains, France.

Église Notre-Dame d'Aix-les-Bains is a Romano-Byzantine church in the town of Aix-les-Bains defined by a green bell tower rising about 55 meters high. The building combines Romanesque and Byzantine architectural elements throughout its structure.

The project began in 1875 on the initiative of the parish priest Pavy, and a design competition was won by architect Arthur Bertin. Construction by the Bonna firm ran from 1890 to 1892, with further modifications continuing until 1905. The building was formerly the collegiate church of Notre-Dame-de-l'Assomption.

The twelve apostle paintings in the choir have been classified since 1976; expert assessments suggest they come from Italy and date to the 17th century. The Stations of the Cross came from Spain, brought back by General Forestier during Napoleon's campaigns, and are being considered for the supplementary inventory of historic monuments.

The church sits on Boulevard des Côtes and is open to visitors on most days. It is wise to check current opening hours upon arrival and avoid times when religious services are taking place.

The church grounds serve as a public parking area during weekdays, merging religious and urban functions. This dual use shows how the building integrates into the town's daily life.
