description Preseli Hills Overview
The Preseli Hills (Welsh: Mynyddoedd y Preseli) are an upland moorland range in north Pembrokeshire, Wales, rising to approximately 536 metres at Foel Cwmcerwyn, the highest point. They are geologically significant as the source of the spotted dolerite 'bluestones' that form part of the stone circle at Stonehenge in Wiltshire, England, some 240 kilometres away. The hills contain numerous prehistoric monuments, including Neolithic burial chambers and Bronze Age standing stones. The landscape consists primarily of open heath, blanket bog, and rough grazing land.
