The Ramparts of Vannes are the fortifications built over fourteen centuries to defend the city of Vannes in the Morbihan department of Brittany, France. Originally founded by the Romans at the end of the 1st century BC under Augustus, the settlement was first fortified as a castrum at the end of the 3rd century during the crisis of the Roman Empire. This initial enclosure stood as the city's sole protection for over a thousand years. Under Duke John IV in the late 14th century, the walls were substantially rebuilt and extended southward to encompass new districts and accommodate the Château de l'Hermine, effectively doubling the enclosed area. The Wars of the League prompted the addition of several polygonal bastions—Gréguennic, Haute-Folie, Brozilay, and Notre-Dame—while the Garenne spur was constructed around 1630 as the final defensive structure. Urban development in the 19th century saw the destruction of segments of the northern and western walls; concerted heritage preservation efforts began only after 1886 and were formalized with a protection campaign established between 1912 and 1958. Today, the Ramparts of Vannes represent among the finest surviving urban fortifications in Brittany.
