The Callanish Stones are an arrangement of standing stones placed in a cruciform pattern with a central stone circle. They were erected in the late Neolithic era, and were a focus for ritual activity during the Bronze Age. Archaeological excavation in the 1980s proved that the main circle was erected 4,500-5,000 years ago, and the chambered tomb a few generations later. The setting has a unique arrangement, with lines of stones radiating in four directions from the ring. It is not fully clear whether the stone alignments were constructed at the same time as the ring, or later. The layout of the site, along with many others across the British Isles, appears to have an association with astronomical events, the precise nature of which cannot be determined.
Numerous other ritual sites lie within a few kilometres. These are mainly more modest rings of standing stones, or single monoliths. The most impressive Cnoc Ceann a' Ghàrraidh and Cnoc Fhillibhir Bheag lie just over a kilometre south-east of the main Calanais ring, and originally consisted of rings of stones at least eight in number.

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.
