Long Howe

The hazelnut was found in a layer beneath the Bronze Age burial mound at Longhowe during excavations earlier this year. The charred shell has been dated to 6820-6660 BC, and its discovery pushes back the known settlement of Orkney by 3,000 years. Mesolithic settlement has long been known from stone tools, but the nut has provided the first definite date.
