Saint-Martin church is a homogeneous building with an elongated plan. It was rebuilt in 1837, as indicated by the date on a pedestal of the western portal, on the site of the old church, which dated from the 12th century (according to Abbé Roussel), thanks to the generosity of the Marquis de Rose and the parishioners. The north chapel surmounts a funerary crypt of the various families who have owned the seigneury of Dammartin, notably the de Rose family. The nave has three ships of seven bays: the central ship is covered by a barrel vault and the side aisles have ceilings. The nave's three aisles are covered by a single roof. The nave is preceded by a tower-porch crowned by a square slate spire and its base is flanked by two chapels. The choir consists of a straight bay covered by a false barrel vault, followed by a semicircular apse with a false barrel vault. The right-hand bay is flanked on the north by a seigniorial funerary chapel (cross-vaulted) and the sacristy on the south. The walls are of ashlar sandstone, except for the facade's quoins, which are of ashlar limestone.
