Église Saint-Aignan de Brinay, church located in Cher, in France

Église Saint-Aignan de Brinay is a Catholic church in Brinay, Cher, made up of a rectangular nave added in the 12th century and an 11th-century choir of the same plan, joined by a round arch. The nave has a wooden barrel vault and round-arched windows. A 19th-century caquetoir stands before the entrance, and a 17th-century tower with a slate spire rises behind the gable.

The choir was built in the 11th century as a chapel; the present nave was added to it in the 12th century, covered with a wooden barrel vault and linked to the choir by a rounded arch. The bell tower dates from the 17th century and its bell bears the year 1685. The caquetoir porch was built in the 19th century, and the church was classified as a monument historique in 1972.

The choir's 12th-century murals run in two registers on the north, east and south walls, showing the main events of Jesus's life before the Passion; the west wall carries prophets and evangelists. On the intrados of the arch between nave and choir are scenes of the labours of the months, dated by the peasants' clothing, hairstyles and gestures to around the mid-12th century.

The church stands in the village of Brinay, in the Cher department. The entrance is through the 19th-century caquetoir, the porch in front of the nave; the choir with its 12th-century murals lies beyond the rounded arch. The building has been classified as a monument historique since 1972.

The building contains 12th-century wall paintings discovered in 1911-1912 that depict religious scenes and monthly labor cycles across the choir walls. These rare frescoes showcase medieval artistic skill and offer insight into how faith and practical life were intertwined in that era.
