At about 40m long, Carlungie Earth House is one of the largest and most complex examples of its kind in Scotland. It was accidentally discovered during ploughing in 1949. Subsequent excavations during the following two years also revealed about eight associated stone dwellings at ground level.
Earth houses, or souterrains as they are also known, were not dwellings, but stone-lined underground passages which typically date to the Iron Age. They’re found along much of eastern Scotland, as well as in Ireland, Cornwall and Brittany.
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.
