The Château de Kérouzéré is a Breton manor castle built in granite in the first half of the 15th century for Jean and Yves de Kérouzéré, seneschal of Morlaix, and followers of the dukes of Brittany. Visible from the sea, Kérouzéré was dangerously exposed and was particularly vulnerable to English attacks. As such the duke permitted him to erect a single tower of more than twenty-four feet in width with crenellations and ditches. This construction caused a major controversy with the neighboring seigneur of Kermorvan. As a result, from 1466 the building was always unfinished and, in 1468, François II had to grant a second authorization for its completion. The original tower is the part of the manor-house located to the west of the current entry (the window of the chapel sits above it).
It was besieged in 1590 during the French Wars of Religion and seriously damaged as the southeast tower was destroyed. It was rebuilt around 1600. There are four superimposed halls: the lowest hall is on the right of the entry and the upper-hall, arranged in the roof, gives access to the covered wall-walk. The kitchen, the common rooms and the private quarters, above, are directed towards the west. There were originally four corner towers; the moat, of which vestiges remained until the last century, has been filled in. The interior of the manor-house still has some 17th century wall paintings. The roof of the northwest tower was restored at the end of the 19th century.
Today visitors to the castle can still see the armoury, chapel, stairs, wall-walk and the watchman's tower with a view over the sea. There is also a 15th-century dovecote still standing on the grounds.
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).
