Marble Arch

Marble Arch is shown as a cliff on the public map of Swansea. The saved point is the map point or the centre of its mapped shape.

Marble Arch is a coastal sea cliff feature located near Swansea, formed from Carboniferous limestone, approximately 300 to 360 million years old. The arch and cliff were shaped by differential erosion, where softer rock layers were worn away faster than the more resistant limestone, creating a striking natural archway notable for its coastal geomorphology.
