About the Elan Valley Ancient Sites Project
This project explores and records the prehistoric landscape of the Elan Valley, including cairns, standing stones, stone circles, stone rows, cists and settlement remains across one of the most remarkable upland archaeological landscapes in Mid Wales.

This map shows the wider area covered by the site pages and the ancient landscapes recorded across the Elan Valley.
Sites in the database
The database continues to expand as more sites are visited, photographed and added to the project.
The Project
The Elan Valley is best known for its dramatic reservoirs and upland scenery, but it is also rich in prehistoric archaeology. Across the hills and moorland are burial cairns, standing stones, stone rows, cists, hut circles and other ancient remains.
This website brings together photographs, descriptions, map references and area guides to help document these sites and make them easier to explore. Some monuments are well known, while others are remote, overlooked or only rarely visited.
The aim is to build a clear and growing record of the ancient landscape of the Elan Valley and the surrounding hills near Rhayader.

Many of the monuments recorded on this website are in remote upland locations. Access can involve rough ground, steep slopes, boggy areas and rapidly changing weather.
Please take care when visiting, respect private land and local access guidance, and avoid disturbing any archaeological remains. These places have survived for thousands of years, and preserving them matters.
Always leave monuments as you find them and help protect the historic landscape of the Elan Valley.
