Église Notre-Dame-de-l'Assomption de Brethenay, Gothic church in Brethenay, France.

Église Notre-Dame-de-l'Assomption is a 13th-century Gothic church with a continuous rectangular plan of five rib-vaulted bays, four for the nave and one for the choir. Its south wall carries a square bell tower added in the 15th century, topped by a steep grey spire with a white clock face. The west portal is sheltered by a wide three-sided roof porch on an impressive timber frame.

The building was constructed in the 13th century to serve the spiritual needs of the local parish. A bell tower was added to the south wall in the 15th century to enable the church to call the community together.

The church houses 17th-century carved figures of saints that reflect religious beliefs held by local people over centuries. These sculptures show the folk art traditions and spiritual practices that mattered to the community.

The church is located in a village setting and can be easily reached on foot from the center of Brethenay. Visitors should expect that access may be limited to certain times or days, as is common with rural churches.

The west portal is covered by a wide porch whose three-sided roof rests on a heavy timber frame. The 13th-century church was listed as a monument historique on 23 December 1925. Inside are four 17th-century popular-art statues: Saint Mammès, the Vierge de l'Assomption, Saint Roch and Saint Nicolas.
