About

La Roche-Derrien is one of the most original Petites Cités de Caractère in the Trégor. Founded as a stronghold on a promontory overlooking the Jaudy, it keeps a medieval street plan, old houses and a very rich history. The battle of 1347, a major episode in the War of the Breton Succession, is now told in the church of Sainte-Catherine through a binaural sound experience. The village is also nicknamed Kapital Stoup, the capital of tow, after the linen work that long made it prosperous. The La Roche 3D trail adds a playful touch with tablets, augmented reality and reconstructions. From the Calvaire chapel, the view over the Jaudy valley is remarkable. The town is open to visitors all year, and guided tours of about 1 hour 30 are on offer.

Tips on the spot

Arrive before 10 am in high season for fewer people; late afternoon is also calmer.
Use the official car parks and finish on foot; on market days or big events, allow more time to park.
Wear good shoes for cobbles, quays, paths and steps.
Start at the tourist office or an interpretation trail if there is one; guided tours give a much richer reading of local history.
Check the opening times of monuments and activities on the day; in winter, some close earlier.
