Donjon Lacataye

The Donjon Lacataye is the keep of a 14th-century castle, constructed by order of Gaston Phébus in the commune of Mont-de-Marsan in the Landes département of France. Today, it houses the Musée Despiau-Wlérick.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. The material used is coquillère, a local sedimentary rock.
