The Hebrides were settled early on in the settlement of the British Isles, perhaps as early as the Mesolithic era, around 8500-8250 BC, after the climatic conditions improved enough to sustain human settlement. There are examples of structures possibly dating from up to 3000 BC, the finest example being the standing stones at Callanish, but some archaeologists date the site as Bronze Age. Little is known of the people who settled in the Hebrides but they were likely of the same Celtic stock that had settled in the rest of Scotland. Settlements at Northton, Harris, have both Beaker & Neolithic dwelling houses, the oldest in the Western Isles, attesting to the settlement.
