Château de Loyat

Château de Loyat is a historical castle in Loyat between Josselin and Brocéliande, built with stone walls and designed with symmetrical proportions. The building is accompanied by formal gardens that spread across the grounds, creating a balanced landscape composition.

The castle was built between 1718 and 1734 by architect Olivier Delourme for René-Charles de Coëtlogon, replacing a deteriorated manor on inherited land. This new construction transformed an old estate into an architectural statement.

The castle received backing from Marquis Alain-Emmanuel de Coëtlogon, an adviser to King Louis XIV, who involved members of the Royal Academy of Architecture. This royal influence shaped the refined style of the building and its formal gardens.

Visitors should reserve in advance to take guided tours of the castle and its grounds. The visits provide access to the well-preserved 18th-century architecture and formal gardens throughout the property.

Construction faced significant obstacles due to the remote location and poor road conditions, which complicated the transport of local building materials. These difficulties demonstrate how challenging it was to execute such an ambitious project in rural Brittany.
