Tréguier: Cathedral, half-timbered houses and estuary

Tréguier offers several distinct ways to shape a stay: the architectural history of Saint-Tugdual Cathedral, half-timbered houses, and the Jaudy and Guindy estuary. If you enjoy looking at historical details, you can focus on the building phases, decoration and individual memorial sites; if you prefer exploring on foot, the marked Tro Landreger circular walk is a good option. The treasure hunt and sightseeing offer further ways to explore. This makes it easy to plan each day around your own interests.

Saint-Tugdual Cathedral: Building Phases and Historic Monument

The former Saint-Tugdual Cathedral and its cloister have been protected as historic monuments since their listing in 1840. Construction of the cathedral began in several phases from the mid-13th century onward. The west portal was completed around 1356; the nave and choir were built between the late 13th and early 15th centuries. The portal therefore marks a dated phase in a longer sequence of construction, not the date of the entire building.

The cloister is designed in the Flamboyant Gothic style and was built by Pierre Le Tirant and Rolland Le Besque. The tomb of Saint-Yves is also located in the cathedral. The 18th-century spire rises more than 60 metres above the entire town. Together, these features highlight different aspects of the building: a church built over several phases, a cloister with named builders, and a landmark that towers above its surroundings.

Half-Timbered Houses and Chapel

Maison du Tisserand, house no. 22, is one of the few houses in Tréguier with two overhanging half-timbered walls. Paying attention to its construction offers a different perspective on the town’s architecture than the church: here, the focus is on a single house and its half-timbered structure.

The Chapelle des Paulines was built in 1760. Its features include trompe-l’œil draperies, a ceiling painted with portraits, and 19th-century stained-glass windows. The draperies create the illusion of painted fabric, while the ceiling and windows add their own decorative touches. The chapel hosts exhibitions, and admission is free during opening hours. As the exhibition programme and access arrangements may change, check the current visiting conditions before your visit.

Estuary and Circular Walk

The Jaudy and Guindy meet near Tréguier. Influenced by the tides, they form the estuary, known as the Ria or Rivière de Tréguier. Ria and Rivière de Tréguier are names for this estuary.

The Tro Landreger is an easy 6.2-kilometre circular walk starting in Tréguier. Marked in yellow, the walking route follows the banks of the estuary and local paths. Its length, circular layout and starting point provide practical details for planning a walk. Markings and route details may change; check them before setting out.

Tours and Discoveries

At Maison Ernest Renan, you can explore the building and its garden at your own pace. As visiting arrangements may change, it is advisable to check before you travel.

Le Mystère Abgrall is a treasure hunt through the lanes of Tréguier, where you can discover places steeped in history.
