Origin and history

The Lenest dungeon, also known as Lenet dungeon, is a fortified building located in Saulgé, Vienna, New Aquitaine. Originally, the site was a feudal motte on which was built a dungeon in the 13th century, before being redesigned around the 15th century. This monument illustrates the evolution of medieval defensive systems, moving from a ground structure to a stone fortress, while integrating comfort elements such as fireplaces or painted decorations.

The history of the dungeon is linked to the Lenet family (or Lesnet, Le Net), of Irish origin by an ancestor named Greor d'Esmond, established around 950 in the area after fighting the Vikings. His descendants, allied with the Dukes of Brittany and then with the Counts of Provence, played a notable political and military role. Among them, Pierre Lenet, close to the Condé and mentioned in the letters of Madame de Sévigné, is the most famous figure. The family held positions as a trustee prosecutor in Vannes or a royal senechal in the Rhuys peninsula, while accumulating fiefs such as Noyal-Pontivy or Crédin.

Architecturally, the dungeon presents itself as a three-storey square central body, flanked by four turrets and integrated into a enclosure. Although it is ruined (with no roof), it preserves remarkable elements: cannon guns for defense, monumental chimneys, latrines in a tower, and traces of murals. These details testify to a rare search for comfort for the time, while recalling its defensive vocation in front of armed gangs or robbers. The site, transformed into a farm after the Middle Ages, was classified as a historic monument in 1990.

The coats of arms of the Lenet vary according to the branches: three hunting horns for the Lesnets, an occitan cross topped with horns for the Nesmonds, or a yellow background with a blue band for the Le Net du Motenno-Kerio. These symbols reflect their successive allegiances, from the Dukes of Brittany to the kings of France. The family will also swarm under the names The Nest, The Netz, or Nesmond, leaving a lasting imprint in the history of Poitevin and Breton.

Among the key characters, Jehan de Lesnet was cited as the squire of Richard d'Étampes (brother of Jean V of Brittany) in 1421, while Jean Le Net was Sénéchal and royal notary in the Rhuys peninsula. Their role in managing fiefs and defending strongholds such as La Chèze or Pontivy, at the service of Olivier de Clisson, underlines their integration into regional power networks. The Lenest dungeon thus embodies both a turbulent family history and a military architecture adapted to the challenges of its time.
