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. They are near the village of Callanish (Gaelic: Calanais) on the west coast of Lewis in the Outer Hebrides, Scotland.
The Callanish Stones are situated on a low ridge above the waters of Loch Roag with the hills of Great Bernera as a backdrop.
Numerous other ritual sites lie within a few kilometres. These include at least three other circles, several arcs, alignments and single stones; many visible from the main site. The most impressive Callanish II and Callanish III lie just over a kilometre southeast of the main Callanish Stones, and originally consisted of circles of stones at least eight in number. The existence of other monuments in the area implies that Callanish was an active focus for prehistoric religious activity for at least 1500 years.
