The Neolithic settlement in Scotland, older than Stonehenge and protected as a World Heritage Site, is Skara Brae. It lies on the Bay of Skaill in Orkney and is one of Europe’s best-preserved prehistoric villages.
Skara Brae was occupied roughly between 3200 and 2200 BCE, during the Neolithic period. Its stone-built houses had beds, dressers, hearths, and covered passageways, giving archaeologists an unusually detailed view of domestic life thousands of years ago. A sandstorm exposed the settlement in 1850 after it had been hidden beneath coastal dunes.
Skara Brae forms part of the Heart of Neolithic Orkney World Heritage Site, alongside the Stones of Stenness, the Ring of Brodgar, and Maeshowe. The Ring of Brodgar is therefore a common mix-up: it is another nearby prehistoric monument, but not the settlement named in the question. “Older than Stonehenge” is broadly accurate, since Skara Brae’s occupation began before Stonehenge’s earliest monumental phases.
