Long-distance landscapes: from quarries to monument at Stonehenge.

Stonehenge is famous for the distances moved by its stones, both sarsens and bluestones. In particular, the bluestones have their geological origins in West Wales, 225km away. Recent excavations at two of these bluestone sources – one for rhyolite and one for spotted dolerite – have identified evidence of megalith quarrying around 3000 BC, when Stonehenge’s first stage was constructed. This remarkable movement of bluestones from Wales coincided with a decline in regional cultural distinctions between west and east, suggesting that building Stonehenge may have served to unify the Neolithic populations of Britain.
