Dilsberg Castle is a castle on a hill above the River Neckar. The castle was built by the counts of Lauffen in the 12th century. In the 13th century it became the main castle for the counts. In the 14th century it became part of the Electorate of the Palatinate and received town rights in 1347. During the Thirty Years" War, the castle was considered impregnable until Imperial forces under Tilly took the castle in 1622 after a long siege.
In 1799, French forces tried and failed to storm the castle. A 46-metre-deep well helped keep the defenders supplied during this assault. In the 19th century the castle fell into ruin and was used as a quarry. Today the castle and its town are a tourist attraction and are administered by the Staatliche Schösser und Gärten Baden-Württemberg, attracting thousands of visitors.References:
The Château d'Olhain is probably the most famous castle of the Artois region. It is located in the middle of a lake which reflects its picturesque towers and curtain walls. It was also a major stronghold for the Artois in medieval times and testimony to the power of the Olhain family, first mentioned from the 12th century.
The existence of the castle was known early in the 13th century, but the present construction is largely the work of Jean de Nielles, who married Marie d’Olhain at the end of the 15th century.
The marriage of Alix Nielles to Jean de Berghes, Grand Veneur de France (master of hounds) to the King, meant the castle passed to this family, who kept it for more than 450 years. Once confiscated by Charles Quint, it suffered during the wars that ravaged the Artois. Besieged in 1641 by the French, it was partly demolished by the Spaniards in 1654, and finally blown-up and taken by the Dutch in 1710. Restored in 1830, it was abandoned after 1870, and sold by the last Prince of Berghes in 1900. There is also evidence that one of the castles occupants was related to Charles de Batz-Castelmore d'Artagnan, the person Alexandre Dumas based his Three Musketeers charictor d'Artagnan on.
During the World War I and World War II, the castle was requisitioned first by French troops, then Canadian and British soldiers. The current owner has restored the castle to its former glory.
