In 1957, the Saint Renan marshes revealed a large deposit of tin ore, mined by the Compagnie minière de Saint Renan.

After fifteen years of operation, the deposit was exhausted. Today, seven lakes remain. In the heart of the town, the shores of the "Ty Colo" and "La Comiren" lakes have been landscaped for the enjoyment of walkers.

The smooth waters of the Ty Colo lake were the first in Brittany to host an astonishing board sport: wakeboarding on a cable.
