The Puerta de Palmas is a former city gate built in 1551. It has two cylindrical towers flanking the entrance door. Prince Philip II and Emperor Charles V and date of construction are mentioned on the outer side of the tower. The towers are fortified with battlements and they have two decorative cords at the top and bottom levels. Its entrance is east-facing, and is double-arched and is decorated with medallions of the shield of the Emperor Charles V. It was once used as a prison, but has since undergone many renovations and has been an entrance point to the city.
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).
