Church of San Andrés is an impressive church built in stone in the 16th century. In the same building, several architectural styles are to be seen, from the gothic to the neoclassical and the renaissance. The most Gothic parts are the nearest to the towers. It's the only remaining part of the Gothic building over which the current building was erected. Picturesque columns and archs. In the other part of the church we can see the sacristy, in neoclassical style. In the middle part we can see the stylistic evolution in the building. In the 'crucero' part we can see a Renaissance style. The church has also a baroque and renaissance-style altarpiece. The 18th-century organ, of classical style, is still in use and used for concerts.
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).
