UK | Wales's slate-producing landscape nominated for WH status

An extraordinary landscape shaped by many centuries of slate production has been nominated by the UK government for Unesco world heritage status, a distinction enjoyed by sites such as the Taj Mahal, the Great Wall of China and Stonehenge.

The production of slate in Gwynedd, north-west Wales, has left a landscape dotted with underground workings, terraces cut into hillsides, grey, towering tips and bright blue pools, all nestling within mountains and woodland.
