Coetan Arthur

Coetan Arthur is a Neolithic chamber tomb near St David's Head in Pembrokeshire, featuring a massive capstone that measures about 6 meters long and 2.5 meters wide. A single upright stone supports the entire heavy slab, creating a simple but effective burial structure.

The site dates back to around 3000 BCE, reflecting ancient burial practices from Britain's early agricultural period. Its survival over 5000 years makes it one of the oldest preserved structures in the region.

The name comes from local legends linking the site to King Arthur, who according to storytelling threw the stones from nearby Carn Llidi. This connection shows how ancient monuments became woven into regional folklore over centuries.

The easiest access is from Whitesands Bay car park, following the Pembrokeshire Coast Path toward St David's Head. The route is well marked and suitable for average walkers, though sturdy footwear and weather-appropriate clothing are recommended.

The structure's orientation mirrors the slope of nearby Carn Llidi, suggesting that Neolithic builders deliberately aligned their construction with the natural landscape. This deliberate integration of monument and terrain demonstrates a level of spatial planning that surprises many visitors.
