Origin and history

Boyac Castle, also known as Boyac Manor House, is a building located in Ploërmel, Morbihan, England. This seigneury, mentioned in the 9th century as "Batalaoc", was given to the monks of Redon in 858 by Catwaten, son of Drelawen. The site, known under various names ("Buiac", "Boyat", "Boyac"), was ceded in usufruct to the bishop of Vannes Bily before being returned to the monks in 913. The 1676 description describes it as a "noble house" with a closed courtyard and portal.

The current mansion, built in shale and granite on the edge of the 16th and 17th centuries, combines a body of houses and commons around a closed square courtyard. Defensive-looking pavilions and a multi-faceted forecourt complete the set. Inside, the house retains its original spatial organization, with monumental granite chimneys. Since 2011, the site has remained a private property, partially accessible during Heritage Days.

The castle of Boyac illustrates the evolution of an ancient Breton seigneury, marked by religious donations and architecture characteristic of the manors of the region. Its recent listing underscores its heritage importance, while preserving its private use. The exteriors are visible all year round, while the interiors are discovered by appointment or at cultural events.
