Gilles van Bretagne lived here in the 15th century, a poet and womanizer who lived a merry life, hence the expression "courir le guilledou" (to go on a woman hunt). But his brother, Duke Francis I of Brittany, suspected Gilles of plotting and had him imprisoned. Because he didn't die fast enough, he was then strangled. Before his death, however, Gilles subjected his brother to divine judgment and the duke also died, tormented by remorse

The Château du Guildo is located on a rocky outcrop, on the edge of the Arguenon estuary. This stronghold offered a strategic defensive position. It allowed control of both maritime and land passages. The current version of the castle was built from the 14th century. During excavations, however, traces of a first castle dating from the 11th century were found.
