Csesznek castle was built around 1263 by the Jakab Cseszneky who was the swordbearer of the King Béla IV. He and his descendants have been named after the castle Cseszneky. Between 1326 and 1392 it was a royal castle, when King Sigismund offered it to the House of Garai in lieu of the Macsó Banate. In 1482 the male line of the Garai family died out, and King Matthias Corvinus donated the castle to the Szapolyai family. In 1527, Baron Bálint Török became its owner.
During the 16th century the Csábi, Szelestey and Wathay families were in possession of Csesznek. In 1561, Lőrinc Wathay repulsed successfully the siege of the Ottomans. However, in 1594 the castle was occupied by Turkish troops, but in 1598 the Hungarians recaptured it.
In 1635, Dániel Esterházy bought the castle and village and from that time on Csesznek was the property of the Esterházy family until 1945.
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).
