The abbey church of Sainte-Croix is, according to the tradition, the heir of a chapel built here by St. Helena in the 4th century and of an abbey founded by Charlemagne. Better documented is the creation of an Augustinian abbey by Algar, the new bishop of Coutances (formerly the prior of Bodmin Priory, Cornwall) in 1132. The Romanesque church was consecrated in 1202, being largely remade in the following centuries with successive renovations. The choir was remade in the 16th century while the bell tower is from 1860 to 1863.
During World War II, the bell tower (located laterally) collapsed and it was on its ruins where the body of Major Howie was placed; a new bell tower was rebuilt in 1957 on the forecourt in a modern style. On the church square stands the departmental monument in memory of the victims of the wars of Algeria and Indochina, opened in 2005.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
