Château de Picquigny was built around the beginning of the 11th century and rebuilt over the following centuries. It was severely damaged during World War I. The vestiges are still picturesque and imposing, nevertheless. Outside of the ramparts, there are other medieval buildings: a prison, a kitchen, two cellars, latrines and the Pavillon Sévigné.
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.
