Origin and history
The Château de Conquereuil, also called Château de Pontveix, is located in the commune of Conquereuil, in the Loire-Atlantique region of Pays de la Loire. This historic site consists of four main buildings dating from the 15th to the 17th centuries: a hostellerie linked to the path of Santiago de Compostela, the chapel of Sainte-Marguerite in slate schist surmounted by a lantern, stables, and a dovecote added in the 18th century. The ten-hectare park also houses a Roman road dating back to the 1st century BC, showing its ancient occupation.
Located 2 km south-west of the village, near the Pont Veix (old pass on the Don), the castle marks a strategic point on the old Roman way from Nantes to Rennes. The 15th century hotel, built by the monks of the priory of Marsac-sur-Don to welcome the pilgrims, was the scene of a notable event in 1482: the Duchess Anne of Brittany was invited by Maximilien de la Chênaie. The original medieval castle was replaced in the 19th century by the current building, rebuilt by Porzon de Martel.
Ranked a historical monument since 1954 (inscription of the chapel by decree of 21 October 1954), the estate combines medieval, religious and architectural heritage. Its history is part of the local dynamics of pilgrimage, trade via the Roman way, and seigneurial power, reflecting the social and political transformations from Brittany to the Loire-Atlantique from the Middle Ages to the modern era.
