Saint-Pierre church in Bar-sur-Aube, Gothic religious monument in Bar-sur-Aube, France.

Saint-Pierre church is a Gothic building defined by pointed arches and ribbed vaults that shape the interior space. A wooden gallery runs along the south and west sides of the structure, adding another layer to the building's composition.

Construction started in the 12th century and continued through additions until the 19th century, reflecting periods of expansion and renovation. The lengthy building history led to its designation as a protected historic monument in 1840.

The wooden porch called the halloy, running along the south and west sides, sheltered the town's fairs and also served as a burial place, as parish registers attest. The Saint-Michel chapel had its own revenues, declared in 1609. Inside are funerary slabs from the 15th and 16th centuries, including those of Jean Tautant, Claude Paris and Pierre Floriot.

The wooden halloy porch runs along the south and west sides of the church, so the main approach passes under its timber frame before reaching the door marked "ENTREE". Inside, light wooden chairs with woven seats fill the nave facing the polygonal apse, and the floor is laid with large irregular stone slabs.
