The aqueduct of Fréjus was built in the middle of the first century after the ramparts were in place. It functioned for 450 years until the 5th century. It is 42 km long, with a difference in altitude between the highest spring of Neïssoun and the castellum aquae in the city of 481 m. The aqueduct runs mostly in a covered conduit for 36.4 km and for 1.8 km on bridges and 500 m on walls. Large parts of the aqueduct are still well preserved.

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.
