Mesagne Castle probably dates back to the 11th century, but the royal fortress we see today was designed and built by renowned military leader Giovanni Antonio Orsini del Balzo in 1430. Since then, alterations have been made but there are traces of its use as a fortress.
The castle consists of two main parts: the oldest one is the quadrangular tower which has three floors, the other includes the rooms on the ground and first floor, connected to the tower through a rectangular room with barrel vaults. In the internal courtyard one can admire the portals with bossage and round arches, which lead to the roof garden.
Today Mesagne castle includes an archaeological museum and events auditorium.
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).
