The church of Saints Julián and Basilisa was originally built in the late twelfth century. Two inscriptions are provided, one, on the west window of the portico, dates the work to 1186 and names the sculptor Juan de Piasca, and the other on the baptismal font, states its creation date of 1195. In the sixteenth century, however, the building was heavily reconstructed, leaving only the portico generally intact, albeit walled in. It remained enclosed until the building's modern restoration in 1928. The portico is heavily decorated, including a row of figural and vegetal capitals sculpted in the round, a carved alfiz, and numerous corbels.
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).
