The monolithic church of Saint-Émilion is an 11th century church carved entirely out of a limestone cliff. It is one of the largest underground churches in Europe, with an estimated 15,000 cubic meters of rock extracted. The great hall measures 38 meters long and 20 meters wide, divided into three naves of six bays. Like many medieval structures, the church probably had a rich décor of painted murals; however, only a few bits of frescoes remain. Iconographic works, such as depictions of lions, serpents, centaurs, and cherubim, can be seen on the walls and ceilings, possibly in reference to Psalms. Today, visitors can enter the church and view its catacombs.

Coin is available at Salle des Dominicains.
