Église Saint-Pierre de Jarnac, Romanesque church in Jarnac, France.

The église Saint-Pierre de Jarnac is a Romanesque church with a rectangular floor plan and a square tower positioned at its third bay. Inside, ribbed vaults span the nave and a substantial crypt lies beneath the church floor.

The church belonged to the Saint-Pierre priory, linked to Saint-Cybard Abbey in Angoulême, from the 8th century; Benedictine monks and Augustinian canons served it in the 9th century. A Romanesque façade was built in the 12th century, and a square crypt and flat-ended choir were added in the 13th. After a fire destroyed the vaults in 1562, restoration followed in the 17th century; the nave was re-vaulted in brick in 1847–1849, and the south chapel and sacristy were built in 1874–1875.

The 12th-century crypt of Saint-Michel, classified as a monument historique in 1945, served as the burial place of the lords of Jarnac, including the Chabot family from the 15th century. Its four compartments radiate from a central pillar under ribbed vaults, and medieval wall paintings survive inside. The parish also keeps ties with Jarnac's Protestant temple, whose members descend from 16th-century Huguenots.

The church is open during standard visiting hours and is maintained by the Diocese of Angoulême. Visitors should remember this is an active place of worship, so respectful behavior is needed when exploring the interior and crypt.

Former French President François Mitterrand was baptized here and his funeral was held in this church in 1996. This connection makes it a significant location in recent French history.
