Ring of Brodgar
The Ring is in a significant ritual landscape. Within  there are the two circle-henges, four chambered tombs, groups of standing stones, single stones, barrows, cairns, and mounds. A number of flint arrowheads and broken stone mace-heads were found nearby. They seem to date from the Bronze Age. The nearby Standing Stones of Stenness and its Maeshowe tomb help to make the Ring of Brodgar a site of major importance.
