Pointe de Latte.

Pointe de la Latte, or the Fort of the Rock Goyon.
The fort can be found on a rocky cape, near Cap Fréhel and the town of Plévenon.
The castle was built in the 14th century by the Lord of Matignon, Etienne III Gouÿon. The construction of the castle began in the 1340s.
In 1379, following the return from exile of the Duke of Brittany Jean IV, the castle was besieged by Bertrand Du Guesclin. The castle was attacked and taken a second time during the Wars of Religion in the 16th century, this defeat marking a time of abandonment of the building. It was not until the 18th century, under Louis XIV, that the castle resumed its strategic interest and was bastioned.
It was in service until the end of the First Empire when the evolution of military techniques led to its unsuitability.
This site was chosen because of its favorable location - being difficult for an enemy to attack due to the lack of easy access and, in addition to it offering clear views of the English Channel the Emerald Coast and a large part of the Bay of St-Malo to provide warning of an approaching enemy, the cliffs on which it is built gave excellent protection from any attempted invasion from the sea. Construction materials were easily accessible: with granite coming from the heart of Brittany, sandstone being directly recovered from the surrounding cliffs, and wood was plentiful available from the many forests which existed nearby in medieval times.
The fort was an important strategic point since it was not far from the trade routes connecting Saint-Malo, Normandy and the Channel Islands.
