Glérolles (Latin glerula, 'gravel') Castle was erected by the bishop of Lausanne in 1150 to protect a road from north to south of the Alps. It was built on the site of an ancient Gallo-Roman town devastated by the tsunami in 563.
Glérolles was given in 1303 to the family Palézieux who strengthened it. Bought in private use in 1802 , the castle was transformed to the modern appearance.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
