The capital of the Tricastin, a historic region in the Rhône Valley, Saint-Paul-Trois-Châteaux is an ancient fortified town in Provençale Drôme. It possesses a magnificent medieval heritage represented mainly by its remarkable 12th and 13th-century cathedral. A marvel of the Provençal Romanesque style, its choir contains a mosaic from the same era depicting the city of Jerusalem. The 17th-century high altar of gilded wood, the carved decorations in the nave, and the pipe organ from the early 18th century complete this harmonious interior.
Located at the very heart of the historic centre, the cathedral is the starting point for a wander along the cobbled streets of Saint-Paul-Trois-Châteaux. On your walk, you can not only admire Renaissance-style mansions but also relics from Roman and medieval times.
Let your curiosity lead you all the way to the Chapel of St. Justus, perched on a rocky spur accessible via a marked footpath of around 2.5 kilometres. Up there, the 360° panoramic view of Saint-Paul-Trois-Châteaux and its surroundings is quite simply exceptional!
The Tricastin is a major centre for black truffle production. Opposite the cathedral chevet, the House of the Truffle and the Tricastin has a fun and interactive exhibition telling the story of this unique mushroom, the region's black diamond.
