Neuravensburg Castle was built at the end of the 12th century by the Counts of Argengau, mentioned in 1271, and destroyed in the Peasants' War of 1525. From 1614 to 1617, the castle was reconstructed and expanded into a castle by Abbot Bernhard Müller of the St. Gallen Abbey. In 1836, the castle was sold for demolition, and from 1837 to 1845, it was partially dismantled.
In 1992, the city of Wangen purchased the castle ruins and carried out further restoration work from 1995 to 1996. Besides the keep ruins with a viewing platform, which is accessible from the inside, the foundation walls of the palace are still preserved. The entrance to the castle ruins is located at Hagmühleweg. Following its establishment in 1987, the Neuravensburg Castle and Homeland Association took over the responsibility for the preservation and research of the castle complex.
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.
