The Château de Suscinio or de Susinio is a Breton castle, built in the late Middle Ages, to be the residence of the Dukes of Brittany. It is located in the commune of Sarzeau in the département of Morbihan, near the coast of the Atlantic ocean. The spectacular site comprises the moated castle, a ruined chapel, a dovecote, and a few ruined outbuildings. History 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. The castle was fortified and enlarged, at the end of the 14th century, when the heirs of the duchy had to fight to keep their assets (Brittany was not yet fully united to France and did not become so until 1514), after the castle was taken by Bertrand du Guesclin, the infamous Constable of France. John V and John VI constructed a new seigniorial residence block with a large, new corner tower known as the Tour Neuve. A casemate was added at the end of the 15th century to protect artillery pieces.

Since the castle could only house some 100 persons, the rest must have been billeted close about, in Kermoizin and other villages nearby. Francis II, Duke of Brittany supported this group of exiled Englishmen, against all the Plantagenet demands that he should surrender them. 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.
