The Orcadian archipelago is a museum of archaeological wonders.The Orcadian Neolithic is home to some of the bestpreserved Neolithic sites in Europe: here we can find evidence of a dynamic society with connections binding Orkney to Ireland, to southern Britain and to continental Europe. Yet there is much that remains unknown about the societies that created these sites.In Orcadia, Mark Edmonds traces the development of the Orcadian Neolithic from the early fourth millennium BC through to the end of the period nearly two thousand years later, using artefacts, architecture and the wider landscape to recreate the lives of Neolithic communities across the region.
