The Clava Cairns are a locally known
prehistoric ritual site. These stone circles are aligned with the
Winter Solstice, opposite of Stonehenge with it's Summer Solstice.
On a morning of the Winter Solstice, light
would have found it's way into the inner chambers of these stone
structures.
In some of these they have found human remains,
along with personal items they may have been interred with.
