Origin and history

The Château de Beaumont, located in Mordelles en Ille-et-Vilaine, is a 4th quarter of the 17th century (1686) building built on the remains of an ancient castral mound. This medieval site, still partially visible, included a large rectangular courtyard, a pond, and ditches. The chapel, dated from the end of the 14th century, still remains, while the original castle, in ruins at the beginning of the 17th century, was replaced by the current house body.

The present building, in modern style for the period, was completed in the eighteenth century by two pavilions, then in the nineteenth century by commons and a greenhouse. The old moats were remodeled into a hydraulic network, and the earth lifts planted with charmile. The interior, redesigned in the 19th century, nevertheless retains a remarkable staircase of origin. The estate also includes an orangery, a garden corresponding to the old courtyard, and a moth with its ditch.

Ranked a Historic Monument since 20 March 1995, the castle protects its home, chapel, pavilions, hydraulic system and medieval structures. The site illustrates the architectural evolution of a seigneurial, moving from a medieval fortress to a 17th to 19th century residence, while preserving traces of its defensive past.

The available sources (Wikipedia, Monumentum) highlight the archaeological richness of the place, where the castral moth and its surroundings offer a rare legibility of medieval developments. The Napoleonic cadastre also attests to the disappearance, in the 19th or 20th century, of a second hill or mill located in the northern lower court.
