The amazing Ring of Brodgar, Orkney Islands (Scotland).
The Ring of Brodgar (or Brogar, or Ring o’ Brodgar) is a Neolithic henge and stone circle on the Mainland, the largest island in Orkney, Scotland. The ring of stones stands on a small isthmus between the Lochs of Stenness and Harray. This is the northernmost example of a circle henge in Britain.
It is thought to have been erected between 2500 BC and 2000 BC, and was, therefore, the last of the great Neolithic monuments built on the Ness.
The stone circle is 104 metres in diameter (the third largest in the British Isles). The ring originally comprised 60 stones, of which only 27 remained standing. The stones are set within a circular ditch up to 3 metres deep, 9 metres wide and 380 metres in circumference that was carved out of the solid sandstone bedrock by the ancient residents.
Examination of the immediate environs reveals a concentration of ancient sites, making a significant ritual landscape. Although its exact purpose is not known, the proximity of the
Standing Stones of Stenness and its Maeshowe tomb make the Ring of Brodgar a site of major importance. The site has been recognized as part of the "Heart of Neolithic Orkney" World Heritage Site in 1999.
