Tips from the Community
The Bourigan windmill is an old windmill that has lost its sails but is distinguished by its "large head" (a typical shape for a windmill with a massive body). It was heightened in the 20th century, giving it a unique profile. Although it is not open to the public, this windmill remains an emblematic vestige of Breton rural heritage, marking the region's milling history.

It's a truly wonderful experience when the lock is opened for the sailing ships. This exciting spectacle, as the road is closed, the drawbridge is raised, and the sailors enter and exit the lock, is not to be missed.

The Story of François and Thérèse Mitaillé On August 7, 1944, in the final chaotic weeks of the German occupation, François Mitaillé and his younger sister Thérèse left their home in Penhap, a small hamlet near Marzan. They wanted to return to the farm to tend to the animals. On their way, they were stopped by German soldiers, taken away, and never seen alive again. Days passed, then weeks. The village lived between hope and fear. Finally, it was their own father who, after an endless search, found their bodies—tortured and shot. The loss was immeasurable, not only for their family, but for the entire community. The memorial commemorates François and Thérèse, brother and sister, who were torn away by the violence of war in the prime of their lives. It stands here as a silent witness and a warning that freedom can never be taken for granted.
