A very special site
Sites of Special Scientific Interest (SSSIs) are this country's very best wildlife and geographical sites. They include some of the most spectacular and beautiful habitats in Britain. Dolaucothi has been designated as both a geological and biological SSSI. As well as being the only known Roman gold mine in Britain, Dolaucothi is the first recorded place featuring a rare mineral called cookeite. It's found in part of the mine that's now flooded.
