Église Saint-Jean-Baptiste de Crémieu, Catholic church in Crémieu, Isère, France

The Église Saint-Jean-Baptiste is a hall church built from 1317 on a north-south axis, with a rectangular plan, a flat chevet and a nave of three vessels. Its chevet merges into the town rampart, pierced by a large central bay in the second half of the 14th century. The original oak-panelled ceiling was replaced by neo-Gothic rib vaults, and the walnut stalls date from the 17th century.

The building was constructed in the early 14th century and was originally connected to the Augustinian monastery. A bell tower was added in the early 1500s, and the church underwent various modifications over the centuries while retaining many of its original features.

This church served as the spiritual hub for the Augustinian monastery and remained central to community life in Crémieu. Today residents gather here for religious ceremonies and important celebrations, showing how it continues to connect people through shared traditions.

The church is located in the heart of the old town and is easily accessible on foot, with sturdy stone walls and straightforward interior layouts. Visitors can freely explore the vaulted ceilings and side chapels to get a sense of the building's full structure.

The west wall carries a monumental late-14th-century composition of about twenty scenes, including the double Apostolic and Prophetic Creed; specialists consider it the first work of such scale in a French house of Augustinian hermits. The church also holds the oldest organ in the Isère department, mentioned in the Ollivet chronicle published in 1785.
