Dating from c. 4600 BC at the earliest, Le Petit Mont is one of the most significant Cairns in Brittany, but unfortunately one of the most brutaly vandalized. The cairn measures 60 meters in length, 46 meters in width, and between 6 and 7 meters in height. It is built over several dolmens with antechambers. The dolmen in the southwest has engravings that include axes in circles, fitted axes, and undulating signs. The Romans transformed the site into a sanctuary for Venus.
In 1943, German troops built a bunker and Flak emplacement into the South East Corner of the cairn, which completely destroyed one of the chambers and caused the collapse of the second one pictured above, which has since been restored.
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.
