Origin and history

The church of Saint-Martin de Piennes-Onvillers, located in the Somme department in the Hauts-de-France region, finds its origins in the 9th century, when a first place of Christian worship is attested in the village. In the 12th century, the monks of the abbey of Saint-Corneille de Compiègne established a monastery, in particular the barn of the local tithe. The construction of the current building began at the end of the 15th century, probably under the direction of Jean Vaast, architect of Beauvais Cathedral, for the vaults. The church, in flamboyant Gothic style, is built in stone and covered with slates, with a particular plane where the central nave is flanked by bottoms perpendicular to the five spans.

In the 17th century, the church suffered major damage during the Spanish invasion in 1636, where the choir was burned by the soldiers of Ottavio Piccolomini. A century later, in 1792, the French Revolution marked a new turning point: the bell tower's cross was cut down, the seigneurial vault desecrated, and the building turned into a saltpetre factory. Despite these vicissitudes, the church was classified by decree of 6 April 1908, recognizing its heritage value.

In August 1918, during the Hundred Days offensive, the village of Piennes-Onvillers was bombed, reducing the building to a few walls. A complete restoration was undertaken between 1920 and 1933, during the inter-war period, allowing the restoration of characteristic elements such as the double gate in basket handle and the flamboyant Gothic windows. Inside, only the 16th century baptismal fonts survived the destruction, while the furniture, including a work bench, was completely lost.

Today, Saint Martin's church is distinguished by its bell tower with a slate arrow and its rounded apse. Its history reflects the political and military upheavals that marked Picardia, while illustrating the resilience of local communities attached to their religious heritage. The building, owned by the commune, remains a major architectural and historical symbol in the landscape of Hauts-de-France.
