La Roche Derrien nestles between the old historic towns of Treguier (5km), Paimpol (15km) and Lannion (15km). In the Middle Ages La Roche Derrien, meaning Town of the Rock, was a fortified town over which many battles were fought. The castle at the time was besieged during the War of the Breton Succession and was fought over by the English, French and Bretons. Today it offers beautiful walks on the bank of the River Jaudy. Several timber framed houses line the market square and the church, which dates back to the 12th and 15th centuries, has an elaborate 17thC altar. The stained glass in the church depicts the battle between the French and the English.
