Great stop off for lunch… however, food outlets close between 13:00 - 14:00 or 15:00.

The Saint-Gobrien Church is one of the few Romanesque buildings in Brittany. Inside, you'll discover over 400 square meters of ancient frescoes, dating from the 12th to the 17th century. A stunning visit, combining spirituality and painted heritage.
