The most interesting features of the parish close in Sizun are the triple triumphant doorway and the ossuary-chapel with its triple arching, dating from 1585-1588. In the ossuary is a small museum devoted to local traditions. The 16C church, altered in the 17C and 18C, is crowned by a panelled vault with attractive ornamentation. The organ case, high altar and altarpieces are 17C, as is the canopy over the baptismal fonts. The Treasury is the most significant of Brittany.
