The Donjon Lacataye is the keep of a 14th-century castle, constructed by order of Gaston Phébus in the commune of Mont-de-Marsan.
La Cataye consists of two joined Romanesque houses, which one sees perfectly while entering the current museum whose central internal wall includes Romanesque windows, a sign that one of the two houses was built before the second. These houses belonged to the Viscount's family and were more or less abandoned starting from the 15th century, when the Viscounts moved away from their town of origin. During the 16th century, their upper parts were modified and they were equipped with crenellations.
In 1860, Antoine Lacaze, mayor and owner of the keep, gave it to the town to house troops. It later became the departmental barracks until 1875, when the soldiers moved to the Bosquet barracks in the town. The keep preserved the name Caserne Lacaze (Lacaze Barracks) for nearly a century, in spite of a succession of civil uses: boarding school for young girls, gymnastics centre, municipal workshop.
In 1968, mayor Charles Lamarque-Cando inaugurated in the keep a museum of modern figurative sculpture (the Musée de Mont-de-Marsan), dedicated to two local artists, Charles Despiau and Robert Wlérick.
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.
