Cnoc Ceann a' Ghàrraidh No 2 Stone Circle near Calanais, Isle of Lewis Outer Hebrides, Scotland. SCO 6272
The tallest of the stones marks the entrance to a burial cairn where human remains have been discovered. An excavation campaign in 1980 and 1981 showed that the burial chamber was a late addition to the site, and that it had been modified a number of times. Pottery finds suggested a date of 2200 BC for the erection of the circle. It has been speculated, among other theories, that the stones form a calendar system based on the position of the moon. Professor Alexander Thom suggested that the alignment of the stone avenue (when looking southward) pointed to the setting of midsummer full moon behind a distant mountain called Clisham. Critics of these theories argue that several alignments are likely to exist purely by chance in any such structure. In addition many factors such as the weathering and displacement of the stones over the millennia mean we can never be certain of any original, possibly intentional, alignments.
