Aiello Calabro Castle was probably buillt in the Byzantine period in the 9th century against Arabian raids. It was besieged four months by Norman count Robert Guiscard in 1065. He lost two of his nephews in the siege.
The current ruins date mainly from the 15th century. In the 16th century it was one of the most powerful castles in southern Italy. Aiello Calabro castle was destroyed by earthquakes of 1638, 1783 and 1905. Today part of curtain walls and towers remain.
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).
