Stones of Stenness in Orkney
The Standing Stones of Stenness is a Neolithic monument on the mainland of Orkney, Scotland. Various traditions associated with the stones survived into the modern era and they form part of the Heart of Neolithic Orkney World Heritage Site. They are looked after by Historic Scotland. Sheep are sometimes put in to graze amongst the stones, reflective of their origin during the time when the Neolithic people were learning agriculture.
