The village of Notre-Dame-du-Guildo on the Côte d’Emeraude sits below the impressive ruin of Le Guildo Fortress that once commanded the estuary of the river Arguenon. It belonged to Gilles de Bretagne, the son of Duke Jean V de Bretagne and Jeanne de France, the daughter of King Charles VI. Following vile conflicts of interest, Gilles was dispossessed of his inheritance in favour of his brother, the future François de Bretagne.

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.

Do not confuse Saint-Pierre, Saint-Patrick and Saint-Pétrock! # St-Pierre is a Galilean fisherman from the 1st century, living under the Roman Empire. # St. Patrick is a 5th century Welshman, who had been taken prisoner by Irish pirates. Released, he left to study in France. Consecrated bishop, he returned to Ireland to convert the pirates to Christianity. # St-Pétrock is also Welsh but in the 6th century. A century after St. Patrick's Day, it is to Ireland that we go to study Christian theology correctly. Once trained, Pétrock returned to the South of England, to Cornwall, to found the monasteries of Petrocson and Bodmin, where he exercised an active apostolate. He met Saint Goran there. After that, he crossed the English Channel to announce the Gospel in Brittany, where more than 30 churches were dedicated to him, often under the name of "Perreux".
