THURSO, SCOTLAND—BBC News reports that a prehistoric site, including a hearth made of stone slabs, a hammer stone, rubble, and tools, has been found in the Scottish Highlands. The possible building may have been part of a larger settlement, according to Pete Higgins of the Orkney Research Centre for Archaeology. Further investigation could reveal if the structure was a broch—a monumental, tower-like roundhouse made of drystone walls, or a wag—a semi-underground dwelling featuring a central aisle made of stone slabs that support a stone slab roof. A well-preserved pig’s tooth suggests someone of high status could have lived there. To read in-depth about archaeology in Scotland, go to “Neolithic Europe's Remote Heart.”
