The 423-metre (1,375-ft) limestone mass of Cribarth overlooks Craig-y-Nos in the valley of the River Tawe. There is evidence that the exposed limestone and silica-bearing rocks on Cribarth have been quarried by man for thousands of years.

Fossilised remains of sea shells in a boulder on Cribarth, showing that millions of years ago, this part of Wales was under the sea!

Image 4: These rusting iron wagons, known as drams, once carried the quarried minerals down to the valley bottom.
