context_page_description: Prehistoric Orkney refers to a period in the human occupation of the Orkney archipelago of Scotland that was the latter part of these islands' prehistory. The period of prehistory prior to occupation by the genus Homo is part of the geology of Scotland. Although some written records refer to Orkney during the Roman invasions of Scotland, prehistory in northern Scotland does not end until the commencement of the Early Historic Period around AD 600.
  There are numerous important prehistoric remains in Orkney, especially from the Neolithic period, four of which form a World Heritage Site. There are diverse reasons for the abundance of the archaeological record. The sandstone bedrock provides easily workable stone materials and the wind-blown sands have helped preserve several sites. The relative lack of industrialisation and low incidence of ploughing also have helped to preserve these ancient monuments. Local tradition hints at both a fear and veneration of these ancient structures that may have helped to retain their structural integrity.

The relative lack of industrialisation and low incidence of ploughing also have helped to preserve these ancient monuments. Local tradition hints at both a fear and veneration of these ancient structures (perhaps inherited from the Norse period of occupation) that may have helped to retain their structural integrity.
  Prehistory is conventionally divided into a number of shorter periods but differentiating these various eras of human history is a complex task – their boundaries are uncertain and the changes between them are gradual. The Paleolithic lasted until the retreat of the ice, the Mesolithic until the adoption of farming and the Neolithic until metalworking commenced. A number of the sites span long periods of time and in particular the distinctions between the Neolithic and the later periods are not clear cut. The extraordinary wealth of structures from the Neolithic is not matched either by the early periods, for which the evidence of human occupation is sparse or non-existent, or the later Bronze Age which provides a relative dearth of evidence. The subsequent Iron Age supported a return to monumental building, especially of brochs.
  Formal excavations were first recorded in the late 18th century and as they proceeded an understanding of the structures involved progressed from little more than folklore to modern archaeological science. The sites discussed are found on the Orkney Mainland unless otherwise stated.
