Tréguier combines architectural and art history with a striking estuary. The places and experiences below offer a range of highlights—from the architectural history of the cathedral to a waymarked circular route.

Estuary and Circular Route

The Jaudy and Guindy rivers meet near Tréguier. Influenced by the tides, they form the estuary known as the Ria or Rivière de Tréguier. The Tro Landreger circular route starts in Tréguier and is an easy 6.2-kilometre walk. The yellow-waymarked footpath runs along the banks of the estuary and along local paths. It offers a chance to experience the river landscape on a clearly described route. The route and markings may change; check the latest information before setting out.

Cathedral and Cloister

The present-day Saint-Tugdual Cathedral was built in several phases from the mid-13th century onwards. The west portal was completed around 1356; the nave and choir were built in phases from the late 13th to the early 15th century. The cloister is in the Flamboyant Gothic style and was built by Pierre Le Tirant and Rolland Le Besque. The cathedral also contains the tomb of Saint-Yves.

The spire is also a distinctive feature of the building: it dates from the 18th century and rises more than 60 metres above the city of Tréguier. The former Saint-Tugdual Cathedral and its cloister are protected as historic monuments under the 1840 listing. Together, the construction phases, cloister, tomb and protected status offer several specific points of interest for a visit focused on the cathedral’s history.

Chapels, Houses and Places to Visit

The Chapelle des Paulines was built in 1760. Its features include trompe-l’œil drapery, a ceiling painted with portraits and 19th-century stained-glass windows. Exhibitions are held in the chapel, and admission is free during opening hours. As the exhibition programme and access arrangements may change, check the latest information before your visit.

At the Maison Ernest Renan, you can freely explore the building and its garden. Visiting conditions may change here too, so check them in advance. The Maison du Tisserand at number 22 offers another glimpse of Tréguier’s architectural styles: it is one of the few houses in the city with two overhanging half-timbered walls. This takes you from notable religious buildings to a distinctive feature of a house.

Scavenger Hunt and Brewery Tour

Le Mystère Abgrall is a scavenger hunt through the streets of Tréguier, leading you to discover places steeped in history. The detective’s dossier can be borrowed from the Tréguier tourist office; check availability in advance. Unlike the circular route, which follows the banks of the estuary, the scavenger hunt focuses on the city’s streets and historic sites.

The tour of Brasserie Philomenn offers a different focus: it shows how Philomenn beer is made, from malting and brewing to bottling and packaging, followed by a tasting. Booking conditions may change, so check them before making plans. This gives you the chance to weigh up architectural history, a waterside walk, a search for historic sites and an insight into beer production as different options for your stay.
