The Barrage Vauban is a weir (barrier across a river designed to alter its flow) erected in the 17th century on the river Ill west of the 'Petite France' district in Strasbourg. It was constructed from 1686 to 1700 by the French Engineer Jacques Tarade according to plans by Vauban. Several stories high, it houses sculptures in its main level and a panoramical terrace on its roof.

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.
