Rhoscolyn lies in the south western corner of Holy Island, Anglesey, Wales, looking out into the Irish Sea. The defining feature of the landscape here is the dramatic, rocky coastline were there are numerous inlets and coves. Anglesey is an important study area for some of the most ancient rocks on our planet and Rhoscolyn is one of the island’s finest geological locations. It offers a spectacular display of complex, folded rocks which were old long before the mountains of Snowdonia even existed. Anglesey has long been, and continues to be, the focus of much interest, world-wide, by research scientists and students alike.
