Château de Kerduel, Medieval castle in Pleumeur-Bodou, France

Château de Kerduel stands in Pleumeur-Bodou beside a small stream and lake, with forest around the grounds. Its main granite lodging dates from the 17th century, with a square tower added to the north facade in 1890. The oldest part is a pink granite wing from the 13th century, containing a large square tower with the so-called Chamber of King Arthur. The chapel has two levels, a lower one for servants and an upper one for the owner, each with its own entrance.

The castle's oldest section, a pink granite wing with a large square tower, dates from the 13th century according to French records, while the English source places the oldest part in the 12th. The main granite logis was built in the 17th century, and a square tower was added to the north facade in 1890. The Kerduel family held the estate until 1477, and four justice stones recall its former seigneurial importance.

The castle's Breton name, Kastell Kerduel, is tied to a legend that King Arthur and the Knights of the Round Table lived here; the oldest room in the pink granite tower is called the "Chamber of King Arthur". Local tales say that on cold winter nights, when the tide is low, Arthur rides from Avalon, identified with the nearby island of Aval, on a white horse.

The castle is a private property at the Kerduel hamlet in Pleumeur-Bodou, reached from the access road; visitors stay on public paths and view the facades and roofs from outside. The chapel has two separate levels, one for servants and one for the châtelain, each with its own entrance.

The 1978 listing covers only the facades and roofs of the castle and its chapel, not the interiors. The chapel itself has two levels, a lower one for servants and an upper one for the châtelain, each with its own separate entrance.
