Manoir de Boyac

The Manoir de Boyac is located near Ploërmel in modern-day France and was established by early medieval Christian settlers. Its origins trace back to a rural estate known as “batalaoc” in the 9th century, situated within a local territory referred to as the plebe Armaël. In 858, this estate was granted to the monks of the Abbey of Redon by Catwaten, the son of a local noble named Drelawen, marking its earliest recorded connection to ecclesiastical authority.

Throughout the 10th century, the manor underwent notable changes in ownership and control. Count Matuédo transferred the estate, then called “Buiac,” in usufruct—meaning a right to use the land without owning it—to Bily, the Bishop of Vannes. Subsequently, in 913, Bily returned the property to the monks of Redon, reaffirming the religious community’s long-standing custodianship. Over several centuries, the name of the estate evolved, appearing as “Boyat” in 914, shifting to “Bouyac” in 1440, then “Bouiac” by 1460, and finally settling into the form “Boyac” from 1513 onwards.

By the 17th century, specifically in 1676 during administrative reforms of royal domains around Ploërmel, the seigneurie of Boyac was described as a noble residence with various dependencies. The manor included buildings arranged around a courtyard enclosed by a gate. Its status and structure during this period reflect its continued importance as a landed estate under noble jurisdiction. In modern times, the entire manor received official recognition as a historic monument on July 1, 2011, preserving its legacy as one of the oldest estates in the region.
