It all begins at the impressive former main entrance to the Old Town, the Prison Gate, which acts as a time machine for visitors. Once you've passed through this time-space portal, you're sure to be immersed in medieval times, as this is the starting point for discovering the overall structure of the city's defensive walls. Proof of the strategic importance of Vannes' location at the bottom of the Gulf of Morbihan, the remains of the Gallo-Roman wall also bear witness to its centuries-old past.
As if created for a course in the evolution of military architecture, this wall also features a succession of fortified gates and defensive towers dating from the 14th and 15th centuries, including the Tour du Connétable, a true symbol of the town.
