Historically Treguier, the capital of the Tregor, is called the “quaint little town” and is home to the Cathedral of St Yves, remarkable for its cloisters and several architectural styles ornamenting the various columns in the nave. You can also visit St Yves' tomb.

Treguier was the birthplace or inspiration for many writers such as Anatole le Braz and the historian Ernest Renan, whose home and birthplace has become a museum.

Wander down the little streets to discover the old convents and the Augustinian monastery, colourful wooden houses, sumptuous residences or other gardens.

Located at the end of the Jaudy Estuary and swept by the tides, the port opens onto the market square and its watch towers.

The Wednesday market is rich with regional vegetables, artichokes, cauliflowers as well as sweet and savoury crêpes, and the not-to-be-missed Breton sweet cake, kouign aman.

In summer, “Wednesdays are holidays”, with a weekly musical performance with musical groups come from all over, including Breton bagadou groups.
