A 4,000-year-old Bronze Age stone circle in the Preseli Hills has been targeted by vandals, leading to increased surveillance at one of Pembrokeshire’s most iconic heritage sites.

The recent incidents at Gors Fawr have triggered alarm. Illegal digging around the base of several stones has caused extensive damage, requiring costly specialist conservation work.

Tomos Ll. Jones, Community Archaeologist for the Pembrokeshire Coast National Park Authority, said: “Gors Fawr is a Scheduled Ancient Monument, legally protected due to its national significance. The damage caused here is deeply concerning – not only does it risk the stability of the stones themselves, but it disrespects the thousands of years of history they represent. Destroying or damaging a Scheduled Monument is a criminal offence. Sites like this have endured since long before written records began. Protecting them is not optional – it’s our responsibility.”

Volunteers from Heritage Watch will now be actively monitoring the site, and Dyfed-Powys Police have been made aware of the situation.

Anyone witnessing suspicious activity or potential heritage crime at Gors Fawr or other protected sites is urged to report it immediately to the police on 101, or via the Dyfed Powys website at www.dyfed-powys.police.uk/ro/report/.

Members of the public interested in helping safeguard Pembrokeshire’s archaeological treasures are encouraged to join Heritage Watch. More information is available at: www.pembrokeshirecoast.wales/heritagewatch.
