The Church of Saint Pierre and Saint Paul in Ancinnes is in its original part from the 11th and 12th centuries. It was modified in the middle of the 19th century by the addition of a transept which gives it the shape of a Latin cross.
The Organ of the Church of Saint Pierre and Saint Paul in Ancinnes was built by the Damiens brothers in the middle of the 19th century (1863) following the late 18th century. It was the work of Abbé Dubois, priest of Ancinnes from 1843 to 1865.
This organ, built by the brothers Louis and Robert Damiens, organ builders in Gaillon (Eure) remains, today, one of the only survivors in the region in working order.
It is a unique instrument due to its size, which can be heard as the Damiens brothers would have wished. They built 85 instruments, including 3 in Sarthe. The others were abandoned, looted or burned.
Previously the Damiens brothers were wheelwrights, which explains the robustness and solidity of their organs. These organs were built to last.
The Ancinnes Organ has about fifteen stops divided between two manual keyboards and a pedal keyboard of 13 notes and 850 pipes.
The 12th century openings of the nave, alternating limestone and roussard, remain in the state of vestiges being walled up or enlarged in the 19th century. In the 12th/14th century, a door was opened in the gable while the bell tower and the choir rose, which retain pointed arches and trefoil tracery. Boucher built the North chapel in 1854. Chadaigne, from Alençon, repainted the entire interior around 1860 representing the Eucharist and the story of Saint Peter. A staircase tower was built against the bell tower in 1895.
