An estuary of prosperous towns
Etymologically, Tréguier refers to 3 rivers: the Jaudy, the Guindy and the Bizien. Its privileged location at the confluence of these rivers made it a prosperous city, one of the 7 historic bishoprics of Brittany.
Further upstream, another Petite Citée de Caractère (Small Town of Character) has taken advantage of its location to become a flourishing commercial town, exporting wine and flax products in particular.
