About
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 on 2 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.
Standing Stones of Stenness – the four remaining megaliths of a henge, the largest of which is 6 metres (19 ft) high.
Ring of Brodgar – a stone circle 104 metres in diameter, originally composed of 60 stones set within a circular ditch up to 3 metres deep and 10 metres wide, forming a henge monument. It has been estimated that the structure took 80,000 man-hours to construct.
