Château d'Hyères was one of the largest castles in Provence. The first mention of the castle dates from 1062. In 1524 and in 1536 the royal armies swept over Provence and Hyères castle was also besieged and conquered. It was reorganised by Charles I of Anjou in 1527 and ultimately dismantled by Louis XIII in a gesture of authority following the destructive religious wars. The castle has been labelled Historical Monument for its important architectural remnants. It offers a spectacular view onto the coast and the islands.
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).
