Rennes

Rennes often gets confused with Nantes, the larger port city downriver, but Rennes is something altogether different—the capital of Brittany and a university town with genuine intellectual energy. Medieval half-timbered houses cluster around the cathedral in the old town, survivors of the great fire of 1720 that leveled much of the city. What rose from those ashes was an 18th-century grid of neoclassical streets and squares, giving Rennes an unusual dual personality: ancient core wrapped in Enlightenment geometry. Today it's a working city, not a museum. Students fill the cafés and bookshops. The Parliament of Brittany, a stunning 17th-century palace, anchors civic life. Two rivers—the Ille and the Vilaine—wind through the center, their banks recently reclaimed as parks and promenades. The food leans Breton: crêpes, seafood, cider. Tech companies and research institutions have moved in over the past two decades, making Rennes feel forward-looking without erasing what came before. It's the kind of place where you can walk from a Renaissance street to a contemporary art museum to a craft brewery in twenty minutes.
