The Ring of Brodgar (or Brogar) is a neolithic henge and stone circle in The Mainland Orkney, Scotland, somewhat similar to Stonehenge in England. The ring of stones stands on a small isthmus between the Lochs of Stenness and Harray. The centre of the circle has never been excavated by archaeologists and scientifically dated, but it is thought that the stone circle was constructed around 2500 BC, pre-dating Stonehenge and many other ancient sites in the British Isles and Europe.

The circle is 104 m in diameter, and one of the largest to be found in the United Kingdom. The henge was comprised of 60 stones, of which only 27 remained

The surrounding area is full of other standing stones and round piles of earth atop prehistoric tombs, making a significant ritual landscape. Although its exact purpose is not known, the proximity of the Stones of Stenness and its Maeshowe tomb make the Ring of Brodgar a site of major importance.
