Château de Buzet-sur-Baïse was built originally in the 10th century and rebuilt in the 12th century. There was actually two castles on the site and the church. Castles were burned down in 1293-1294 by the English army. Today the oldest parts date from the late 13th century. The chateau was restored in the 17th century. With its outbuildings and its park, it was acquired in 2018 by the Buzet winegrowers cooperative cellar and must occasionally host cultural or festive events. It is not open to visitors.
Until then, the old 13th century castle chapel, altered in the 16th century, served as a parish church. Decommissioned after part of the vault collapsed in 1849, its remains remain.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
