The Ring of Brodgar is a Neolithic henge and stone circle in Orkney, Scotland. 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, and therefore broadly contemporary with Stonehenge and many other ancient sites in the British Isles and Europe.
