Biniac has two circular burial navetas that were used around 1400 B.C. and are from an earlier period than the long rectangular constructions like the Es Tudons and Rafal Rubí navetas. The east naveta was built on bedrock and has only one oval-shaped chamber, accessed via a perforated stone slab. Several slabs that had fallen over were found inside. The west naveta is also oval-shaped and the wall on the south side has dry stone cladding, clearly added at a later date.
References: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.
