Origin and history

The ramparts of Hennebont, located in the Morbihan, constitute a fortified complex built around the City-Close from the last third of the thirteenth century. Originally designed to replace a feudal motte dismantled by Duke Jean Le Roux after 1270, they underwent major modernizations in the 14th, 16th and 20th centuries to adapt to the progress of artillery. Their current layout, nearly 900 metres long, makes it the second best preserved enclosure in the department after Vannes. These fortifications played a key role in the siege of 1342 and were partially damaged by allied bombardments in 1944.

The structure includes iconic elements such as the Bro-Erec Two historic gates marked the entrances: the Broerec Gate (east, known as Prison Gate) and the Lower Gate (southwest, now extinct). The enclosure, classified as a historical monument in 1941 and 1947, is now owned by the city and is subject to restorations, such as those carried out in 2015 by volunteers of the Association Buildings Histoire et Architecture Médiévales.

The ramparts reflect the strategic stakes of medieval and modern Brittany, between ducal conflicts, War of Succession of Brittany (1341-1364) and military adaptations. Their exceptional conservation allows us to study the evolution of defensive techniques, from the feudal mottes of the eleventh century to the bastions adapted to artillery. The changes of the 16th century illustrate the transition to bastioned fortifications, while the damage of 1944 recalls their vulnerability in contemporary conflicts.

The site is today a major testimony of the Breton military heritage, supplemented by archival sources (Merimée base) and local initiatives of valorisation. Its classification protects elements such as the Courtine de la Levée (1941) and all remains (1947), highlighting its historical and architectural importance.
