Thunstetten castle manor was built as a country manor house in the Bernese Oberaargau in 1711 to 1713 or 1713 to 1715. The castle was built for the Landvogt Hieronymus von Erlach following plans by the architect Joseph Abeille. The castle remained with the Erlach family until 1746. From 1746 until 1971 it had numerous owners. In 1971 the Stiftung Schloss Thunstetten (Thunstetten Castle Foundation) took over management of the building and grounds. Today rooms in the castle or the entire castle can be rented for events or meetings.
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.
