Drws y Gwynt

Cliff

Why this matters

Drws y Gwynt is a sea cliff composed primarily of Silurian greywacke and slate, formed around 440–420 million years ago through sedimentation and subsequent regional metamorphism. It is notable for its exposure of ancient volcanic and sedimentary rocks that are part of the Caledonide mountain belt, offering insights into Wales’ complex geological history.
