St Lythans burial chamber

St Lythans is a megalithic burial chamber in the Vale of Glamorgan consisting of three upright stones supporting a massive capstone. The structure sits at about 70 meters elevation on rolling grassland and presents a clear view of how Stone Age communities built these chambers.

This burial chamber was built around 4000 BCE as part of the early building traditions of the region. Archaeological investigation began in 1875 when human remains and pottery were discovered during chamber clearing.

The site carries the Welsh name Gwâl y Filiast, reflecting connections to local stories and the region's agricultural past. This linguistic connection becomes apparent when exploring the location and learning about its role in the community's identity.

The site sits on grazing land with pedestrian access from a small roadside parking area accommodating just a few vehicles. Weather-appropriate clothing and sturdy footwear are advisable as the ground can be uneven.

Investigations in 1992 revealed flint flakes and a polished stone axe that emerged from the soil due to erosion caused by cattle. These finds demonstrate how natural processes can expose archaeological materials from ancient times.
