Heart of Neolithic Orkney is a group of Neolithic monuments on the Mainland of the Orkney Islands, Scotland. The name was adopted by UNESCO when it proclaimed these sites as a World Heritage Site in December 1999.
The site of patrimony currently consists of four sites:
Maeshowe – a chambered cairn and passage grave, aligned so that its central chamber is illuminated on the winter solstice. It was looted by Vikings who left one of the largest collections of runic inscriptions in the world.
