The construction of the church dates from the 13th century. The church was extensively restored after the Hundred Years' War and its orientation was changed in the mid-18th century. The building was restored again in the 19th century. During these restorations, the local priest died in 1818. Since a decree of March 27, 1926, the church has been listed as a historical monument. A porch was demolished in the 1970s.

The church is a synthesis of different architectural types. The oldest part, the bell tower, dates from the end of the 11th – beginning of the 12th century. Towards the end of the 12th – beginning of the 13th century, a nave with two bays, vaulted on ribbed vaults, was added to it. For aesthetic reasons, three buttresses were leveled above the vaults. The remains of this first church are still visible. At the end of the 15th century, after the Hundred Years' War, the increase in population led to the enlargement of the nave, which brought the number of bays to five, and to the creation of the side aisles. This well-proportioned building deserves a thorough visit.

A bridge name like that can't be made up. ;)

Saint Martin of Tours is the equivalent of a rock star in the 4th century. Gaul is torn apart by army revolts and the struggle between Greco-Roman and Celtic-Germanic influences. In the middle of all this, Christianity is gradually spreading. And Martin, a former Roman legionary, who became a Christian after cutting his coat in two to give it to a poor man (a very brief story), begins to announce the Gospel in the countryside. Christianity changes the situation in this slave-owning and violent society. Work regains its dignity (Ora et Labora) and Saint Martin will become extremely popular, all the way to Torfou, where the parishioners will take him as their patron saint.

This door, which appears medieval, does not go unnoticed with its two towers and the battlements of its curtain wall. Make no mistake, it was built in 1928 on the initiative of Mrs. Belmont, an American national, then owner of the Augerville castle. This gate now belongs to the commune of Boulancourt.
