Castle Villandraut is a ruined medieval fortress constructed between 1305 and 1312 by Bertrand de Goth after his election as Pope Clement V. Built to serve as his residence during stays in Aquitaine, this sumptuous castle reflects his deep affection for his birthplace of Villandraut. The fortress features six monumental round towers, a wide moat, enclosure walls, and a gatehouse; the south tower was destroyed in 1592 during the French Wars of Religion when Henry IV's forces fired over 1,260 cannons to dislodge Catholic League defenders. Classified as a monument historique since 1886, substantial ruins including towers and walkways remain preserved.
