After an earlier smaller church - dating from 840 - was destroyed during a siege by king Philippe II of France, the current Église Sainte-Trinité was rebuilt in Gothic style in 1240. Following severe damage during the Hundred Years' War, the nave (15th century) and the choir, chapels and portal (16th century) were rebuilt.

An extension to the church was built in such a way that carts could pass through the church unhindered via an arch (PiP3). Such an arch is rare in France and unique in Normandy.

The Sainte-Trinité church has a richly decorated choir and a chestnut wood vault (PiP6).
The church - located right at the foot of Falaise Castle - has been classified as a historic monument since 1889.
