Cathédrale Saint-Corentin (Quimper)
The Gothic cathedral of Cornouaille and a Tro Breizh station, Saint-Corentin is the architectural embodiment of the feudal duchy era: begun in 1239 under Bishop Rainaud, it was the first Gothic cathedral in Brittany and established the 'gothique breton' style. The famously bent axis between nave and choir (unique among French cathedrals) may reflect the pre-existing street plan or the orientation toward a sacred spring. The cathedral's dedication to Saint Corentin — a local Breton saint with a legend involving a miraculous fish — connects the ducal ecclesiastical structure to the Breton-language oral tradition. The ermine symbol of the duchy appears throughout the cathedral interior.

Cathédrale Saint-Tugdual (Tréguier)
Site of the Grand Pardon de Saint-Yves — described as the most important Breton pardon — held annually on the third Sunday of May. The 13th–15th century Gothic cathedral served as a 'laboratory for the gothique breton style' and houses the tomb of Saint Yves (Saint Ervoan), patron of lawyers and the poor, reconstructed from 1882. The striking contrast between black-robed jurists and Bretonnes in traditional coiffes during the procession is one of the most photographed pardon scenes. Tréguier is also a Tro Breizh station. The pardon's continuity from medieval times through the suppression era to today makes it a key witness to ritual survival.

Saint-Malo (old walled city)
The walled corsair city on its granite island represents the maritime-commercial dimension of the Breton duchy. Founded by the monks of Saint-Jean-de-Guildevas and later named after the 6th-century Saint Maclou, Saint-Malo became one of the wealthiest ports in Europe through privateering, cod fishing, and the triangular trade. Its ramparts, built largely under the duchy, still encircle the entire intra-muros city. As a Tro Breizh station and a ducal port, it connects the pilgrimage network to the commercial maritime network that sustained the duchy's independence.

Vannes
The ducal capital of the Montfort dynasty and a Tro Breizh station, Vannes embodies the political heart of the feudal duchy. Duke Jean IV (1365–1399) built the Château de l'Hermine here and expanded the city walls from 5 to 10 hectares. The Cathédrale Saint-Pierre, rebuilt in Gothic style from the 13th century on the site of the earlier Romanesque cathedral, is the seat of the Bishop of Vannes and a pilgrimage destination for Saint Paterne — who was actually a Gallo-Roman bishop, not an insular Celtic monk, a detail that complicates the 'Celtic founders' narrative. The Parlement de Bretagne moved between Vannes, Rennes, and Nantes before settling at Rennes in 1561.
