The Saint-Martin church of Cadillac-sur-Garonne is part of a collegiate church founded at the end of the 15th century by Gaston III de Foix Candale and rebuilt in the 16th century. Attached to the north wall of the city wall, it consists of a single nave and a funerary chapel with ribbed vaults.
Entirely in cut stone (except the rubble sacristy), the Saint-Martin church of Cadillac-sur-Garonne reveals a bell tower with a masonry spire from the mid-19th century. Inside, it is possible to admire terracotta statues of Saint Peter and Saint Paul from the 19th century as well.
