How did the bluestones get from the Preseli Hills to Salisbury Plain?

Asked 26 Oct 2026 by ·3 answers·0·0 following
Most likely: people quarried the stones in Preseli and carried them to Wessex, overland or with a water stage, around 3000…Ahead on the evidence, not yet confirmed. It needs two reviews to be accepted.

Where it stands

Three answers have been proposed. People quarried the stones in Preseli and carried them to Wessex, overland or with a water stage, around 3000… leads, with evidence 4 for, 1 against: supported by its tests. Two are still possible.

Why it matters

The 225 km journey of some 80 stones of 2 to 3 tonnes is the largest known movement of megaliths in Neolithic Europe if people did it; if ice did it, the quarries, the dates and the Welsh connection mean something else⁠[1]⁠[2].
