Snowdonia rock mural by National Theatre Wales 'baked on'

A giant mural of a poem on a rock face in Snowdonia for an outdoor theatrical production has been likened to graffiti after attempts to remove it failed.

Rain was supposed to wash the writing off the slab near Gladstone Rock but there are worries it has been baked on due to the warm September weather.

National Theatre Wales has apologised and said it will rectify the problem.

"We don't want permanent damage," said Martin Doyle, chief executive of the National Mountain Centre in Snowdonia.
