A quote from the conservation documents in Britiain:-
"The Preseli Hills or Preseli Mountains (Welsh: Mynydd Y Preseli / Y Preselau) are a range of hills in north Pembrokeshire, West Wales. They form part of the Pembrokeshire Coast National Park.
The hills rise to 536 metres above sea level at Foel Cwmcerwyn and are dotted with prehistoric remains including evidence of Neolithic settlement. Bluestone from the hills at Carn Menyn, sometimes called Carn Meini, were used to build the inner circle of Stonehenge.The Preseli Mountains are the only known place in Great Britain where bluestone is found."
