Pembrokeshire’s Stone Circles and Monuments feature significant prehistoric, Bronze Age, and Neolithic sites. e These ancient sites, often located in the Preseli Hills, frequently contain bluestones and are historically linked to the builders of Stonehenge. Some of the most signifant sites are listed below.

• Gors Fawr Stone Circle (Near Mynachlog-ddu):
  • One of the few nearly intact Bronze Age stone circles in West Wales, consisting of 16 low-lying stones (some are bluestones) in an oval shape.
  • Located on a marshy plateau, it includes two larger outlying stones that may be aligned with the midsummer sunrise.
  • An avenue of stones is thought to have once linked the main circle to these two outlying stones.
• Waun Mawn (Preseli Hills):
  • Considered one of the oldest stone circles in Britain and a potential source for the stones used at Stonehenge.
  • Though now fragmentary, it once formed a huge circle similar in size to the stone circle at Stonehenge.
• Bedd Arthur (Arthur’s Grave):
  • A small Neolithic horseshoe-shaped stone circle or henge in the Preseli Hills.
  • Folklore suggests this is the final resting place of King Arthur, surrounded by breathtaking mountain views.
• Pentre Ifan Burial Chamber (Near Newport):
  • While technically a Neolithic chambered tomb rather than a circle, this is the largest and most impressive megalithic site in Wales, featuring a massive capstone balanced on uprights.
  • It is located nearby and is a crucial part of the region’s prehistoric landscape.
