Origin and history

The Château du Bois de la Motte is a historic monument located in the commune of Pleslin-Trigavou, in the Côtes-d'Armor department, Brittany. Built in the 15th century, it is distinguished by its island settlement in the middle of a moat pond. The main building, elongated and with little openings, is dominated by a higher central pavilion, styled with mansart, which once housed the mechanism of a drawbridge, now replaced by a stone bridge.

The châtellenie du Bois de la Motte was erected as a banner in 1433, then transformed into a marquisat in 1622 under Jean de Bellouan d'Avaugour-Saint Laurent. This status reflects its strategic and social importance in the region. The castle, with its motte and chapel, forms an architectural complex typical of medieval fortifications adapted to their natural environment. Its designation to historic monuments in 1951 protected its facades, roofs, moats, bridge and park, highlighting its heritage value.

The site, accessible by a nearby departmental road, preserves traces of its defensive past, such as openings intended for beams of the drawbridge. Although the information on its current vocation (visits, accommodation) is absent from the sources, its state of conservation and picturesque setting make it a remarkable witness to Breton castral architecture of the 15th-17th centuries.
