Zennor Quoit is a ruined megalithic burial chamber or dolmen, located on a moor about a mile (1.6 km) east of the village of Zennor, Cornwall. It dates to 2500–1500 BC. Aside from the 12.5-tonne roof, which collapsed some time between 1770 and 1865, the chamber is in good condition.

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.
