Overview

History & significance

The Four Stones is a prehistoric stone setting located in Wales and protected by Cadw under reference RD004. The monument comprises four standing stones arranged in a ritual or ceremonial configuration, typical of Neolithic or Bronze Age sacred landscapes. Such stone settings served purposes ranging from astronomical alignment to territorial markers or gathering places for dispersed communities.

The site sits upon Wenlock bedrock, composed of mudstone, siltstone and sandstone laid down during the Wenlock period of the Silurian, some 430 million years ago. This stable geological foundation provided solid ground for the erection and long-term stability of the standing stones. The local stone resources available in the Wenlock sequence would have offered suitable material for the monument's construction.

As a surviving example of prehistoric monumentality, The Four Stones demonstrates the enduring significance of stone settings within the Welsh landscape. The preservation of four substantial stones across millennia reflects both their original sturdy construction and the monument's continued cultural importance through successive periods of habitation and land use.
