Château de Coëtbo

Château de Coëtbo is a castle in Guer featuring a 17th-century facade with two square pavilions at the ends and a large stone exterior staircase. The estate also includes a chapel, dovecote, gatehouse, and terraced gardens, all classified as historical monuments.

The castle was built in 1620 on the foundations of a medieval fortress and expanded in 1647 by architect Pierre Hureau for the Pontchâteau family. This expansion shaped its current appearance and role in the region.

The coats of arms of Julien de Marnière and Marie Anne du Bois Baudry adorn the main staircase, marking the connections of these Breton noble families. These symbols show how residents displayed their social standing and family ties.

The site is relatively accessible, though the terraced gardens require climbing stairs to reach different levels. Wear suitable footwear if you plan to explore the full grounds and the elevated garden areas.

During the French Revolution, the castle served as headquarters for Chouan armies in Brittany, making it a key site for royalist rebels. These insurgents used it as a strategic base following the Battle of Savenay.
