Ilavský castle dates from the turn of the 11th - 12th century. It was probably founded by Knights Templars and later it served as a monastery. The first document of the castle dates from 1446. The state administration established a state prison in the castle, which, in a new form, has remained there until the present day. There was also a concentration camp during World War II.

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.
