Situated on a hill overlooking the valley of Thiele, the Champvent castle of is on of the best preserved medieval castles in Vaud canton. It was probably built around 1250 by Henri de Grandson. His family occupied the castle until 1336. The castle and the lordship then passed in Burgundy until 1476 when it was burned after the Battle of Grandson (in Burgundian Wars). Champvent castle was rebuilt after 1536 and became a private property.
The construction plan derives its origin from Byzantine architecture and undoubtedly became to the Western Europe at the time of the crusades. Today castle is a rectangular building flanked by round towers.
References: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).
