Stones of Stenness, also called Standing Stones of Stenness, is a henge stone circle monument dating from the Neolithic Age, located on the southeast side of Loch of Stenness on Mainland, one of Scotland's Orkney Islands. The stone circle, together with Skara Brae, the Ring of Brodgar and Maeshowe, belongs to the Heart of Neolithic Orkney, which has been a UNESCO World Heritage Site since 1999.
The name Stones of Stenness is derived from the Old Norse Steinn-nes, a stone elevation in the landscape. In the eighteenth and nineteenth centuries, this stone circle was also referred to by the most likely romanticized term Temple of the Moon. The oldest known written reference comes from Martin Martin in 1716. In 1841 this term was still in use locally. The Temple of the Sun was used for the Ring of Brodgar.
