From the first building of the 11th century, there remain parts of the south transept. The medieval church rebuilt by Abbot Robert de Torigni (c. 1110-1186) was consecrated in 1157. The portal dates from the end of the 11th century. The porch on the southern side of the nave dates from the fourteenth century. From this period we have the transept with its powerful granite pillars, but whose capitals were probably recut in the 14th century. The choir dates from the first third of the 13th century. Its smooth baskets or decorated with hooks, and its bases adorned with a row of pearls, recall the columns of the cloister of Mont-Saint-Michel and the chapter house of Hambye. The gable is perforated with a triplet crowned with a lobed rose, and its very damaged stained glass window depicts scenes from the life of Christ. The 15th century nave, which was restored in the 18th century, opens with a flamboyant porch with streamlined framework.
The 12th century bell tower was raised in the 15th century. Dressed in a saddleback and seated on the crossing of the transept, it is pierced on the upper floor on each of its sides by a twin bay. Its roof is embellished at its base, to the south and to the north, by two small galleries with an openwork balustrade.
