Büren Castle was built in 1621-24 as the residence of the Bernese Landvogt over the area. It was built on the site of four farm houses. Between 1624 and the 1798 French invasion a total of 77 Landvogts lived in the castle. Some of the bullet scars from the troops that invaded in 1798 are still visible on the castle walls. Today the castle is home to the municipal administration and government offices. In 2003 the 17th century murals and other art were restored to their original appearance.

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.
