Angenstein castle was founded in the middle of the 13th century by the for a strategic outpost between Basel and the Jura area. It was owned by the Counts of Pfirt, but half of it was apparently ceded in 1271 to the Bishop of Basel.
After 1557 the castle was destroyed by fires (1494 and 1517) and turned into a residence. The four-storey residential tower was built, which still characterize the appearance of Angenstein. The chapel was built in 1562 with new residential and commercial buildings. Its most important jewelery were three splendid glass windows, donated by the Bishop.
Thirty Years' War, fires and the poor conditions of the changing owners led to an increasing neglect. At the beginning of the 19th century numerous changes were made. In 1951, the city of Basel bought the Angenstein. In 1984 the castle was burned for the last time. From 1988 to 1991 it was completely renovated.
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.
