Santa Lucía del Trampal is a monastic church, one of the few surviving Visigothic buildings. Apparently, the basilica was built toward the end of the 7th century as part of a convent pertaining to the Templar monks, for which it served as a chapel, with a single nave and three chapels in the chancel. Along with the transept, the chancel is the truly Visigothic part, built upon perfectly-angled dressed stone. The main body of the church is believed to have been built around the 14th or 15th century.
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).
