Built in an amphitheater on a slope at the foot of which the Jaudy and the Guindy meet to form, swollen by the tide, the beautiful estuary (or ria) called the Tréguier river, rich in a history of fifteen centuries and a heritage exceptional covering more than eight centuries, Tréguier, the holy city of Brittany, offers its visitors its unique episcopal ensemble, its half-timbered houses, its beautiful shipowner's residences, its narrow streets, its interior gardens unveiled by the carriage doors ajar.
A jewel lovingly described by Ernest Renan, Henri Pollès, Anatole Le Braz and many others.
