Église Saint-Gilles d'Étampes, Romanesque church in Étampes, France.

Église Saint-Gilles is a church in Étampes built of sandstone and limestone on a Latin-cross plan with three vessels on a northeast-southwest axis. Its 13th-century bell tower and lower nave are Romanesque, while the 15th-century choir and transept arms are Flamboyant Gothic with quadripartite rib vaults. The nave vault, painted in 1596, shows Louis IX with the features of Henri III, Saint Michael, Saint John the Baptist, Saint Vincent and Saint John, on a background of crowned fleurs-de-lis and the initials H and L.

Construction started in 1123 when King Louis VI of France established a wheat market in the area, making the church a focal point for the growing settlement. The building was extended and modified across later centuries to accommodate changing needs.

The building reflects changes in construction methods and tastes that accumulated over many centuries. Visitors can notice these layers by observing how different sections show varied stonework, arch styles, and decorative details from distinct building periods.

The building sits on Saint-Gilles Square in central Étampes, walkable from the main town areas. The location makes it easy to visit as part of exploring the town's historic districts and nearby streets.

The 1596 frescoes on the nave vault carry crowned fleurs-de-lis and the initials "H" and "L", and show Louis IX with the features of Henri III, alongside Saint Michael, Saint John the Baptist, Saint Vincent and Saint John the Evangelist, plus a Maltese cross.
