The Saint-Thomas chapel is an isolated chapel adjoining a fairly large cemetery. It houses a listed 12th-century fresco.
The Saint-Thomas chapel lies almost halfway between the hamlets of Châteaugarnier (to the north) and La Bâtie (to the south), on the road from Saint-André-les-Alpes to Thorame-Basse.
The current building is built of sandstone rubble, visible on the western facade, covered with plaster on the other sides. Three buttresses punctuate the north and south facades. The chapel has a simple plan with a single nave and two bays, extended by a semicircular choir. At the rear, to the east, accessible through a door in the chevet, is a semicircular apse, serving as a sacristy, partially covered by a cul-de-four vault resting on a projecting quarter-round moulding. The nave is vaulted with non-joining “simili-arêtes” (Collier) falling on culottes. It is lit by two semicircular bays in the choir and by the oculus above the entrance door. The paving consists of traditional terracotta mallons. The whole is covered with hollow tiles on two rows of genoises. A small, single-bay comb bell tower is located directly above the west facade.
The cemetery, still used by the inhabitants of Chateaugarnier and La Bâtie, extends to the south-east of the chapel. It is divided in two, with the older part against the chevet.
