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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
