Château de Suscinio

Designed to be a place of leisure, between the seaside and a forest full of game for hunting, the castle's first logis seigneurial (seigniorial house) dates from the beginning of the 13th century.

For 11 years, Suscinio was an armed camp, alert against any attempt to kidnap Jasper and Henry and return them to England where they were under attainder and would have been promptly executed as threats to the Yorkist rule.

Duke Francis II supported the failed Lancastrian rebellion and invasion of England in 1483 with 40,000 gold crowns, 15,000 soldiers, and a fleet of transport ships.

When the Duke suffered from one of his periods of incapacitating illness, his treasurer, Pierre Landais, agreed to surrender Henry Tudor to the representatives of the Yorkist King Richard III of England, in return for a pledge of 3,000 English archers to defend Brittany against a threatened French attack.

The remains of a ducal chapel was found in the vicinity outside of the moats; its remarkable tiled floor has been carefully removed and restored and is now exhibited in a hall of the castle.

The castle may be unique in Western Europe because of its restoration to its presumed late-15th-century condition; because many other medieval fortresses made obsolete by the use of cannon in warfare were either dismantled or modernised to become "comfortable country houses".
