The church in Azé, “ecclesia Aziazi”, is quoted in 915 as belonging to Tournus abbey. The present Saint-Etienne’s church in Azé consists of two distinct parts, one part is Romanesque and the other one dates to the 19th century (neo-Romanesque and neo-Gothic style) with a trefoil plan. It has kept from the Romanesque period its bell tower and its apse (renovated later). Its nave, side aisles and two apsidal chapels were built in 1867, using the designs of the architect Berthier. The portal's tympanum represents Christ surrounded by the four evangelists’ attributes (tetramorph).
The Romanesque choir was restored in 2018, highlighting the stained-glass windows of the master glassmaker Didron offered by the Count of Murard in 1869 and illustrating the life of the Virgin and that of Saint-Pierre.
Several works by the artist Michel Bouillot are to be seen: an altar frontal made of earthenware tiles from the ceramist’s Jean-Paul Betton workshop (showing the Supper on Holy Thursday) and two crosses (also made of earthenware tiles, one showing the Christ suffering of Good Friday and, the other one, Christ in the full glory of the Risen on Easter Sunday).
