The Château de Thibault de Termes was a medieval castle in the French town of Termes-d'Armagnac. The construction of castle dates from the end of the 13th century and start of the 14th century for Jean, Count of Armagnac. The keep is 36 m high and includes six levels. Strategically built on a hill which dominates the valleys of the Adourand the Arros, it allowed the d'Armagnac family to keep watch over the frontiers of the province of Armagnac.
Its most famous inhabitant was the founder's son, Thibault d'Armagnac, who fought alongside Joan of Arc. He gave evidence on her behalf at her trial.
The castle belonged to the Armagnac-Termes family until the French Revolution, when it was declared a national asset and sold. Various people owned it until it was bought by the commune in the 1960s. The main building having been demolished, the stone of what remained was used to build the railway line between Port Saint Marie à Riscle. The keep became overgrown until it was bought by the commune in the 1960s and, under the Association du Pays vert de d’Artagnan, restored and turned into a museum.
The tower now houses a museum of Gascon life with exhibits on regional history and culture.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
