The walled town, fortified in the 14th century and modified by the architect Vauban two centuries later, huddles on a small island linked to place Jean Jaurès by a stone footbridge. Just past the citadel's clock tower , look out for the 18th-century Maison du Gouverneur above the main gate. From here, rue Vauban leads to place St-Guénolé, passing numerous stone houses converted into shops, crêperies, ice-cream stalls and galleries. The excellent Musée de la Pêche is housed inside the west gate.
It delves into Concarneau's seafaring traditions using everything from archive film to scale models and vintage boats. You can even clamber aboard the museum's very own fishing vessel, the retired L'Hémérica, permanently docked just outside the city walls.
