A UNIQUE art installation has been displayed deep beneath the feet of Blaenau Ffestiniog residents.

Landscape artist Anthony Garratt has completed work on High and Low, a spectacular painting installation which he has created in Snowdonia.

The installation – which is expected to attract half a million people – evokes a unique and compelling narrative about the history, geography and industrial heritage of north Wales.

It features two giant canvases painted in situ, one of which hangs deep beneath the north Wales mountains in a disused slate cavern at Llechwedd, near Blaenau Ffestiniog.

The first canvas floats on a specially constructed vessel, high on a lake next to an abandoned copper mine on the flanks of Snowdon.

The second Llechwedd piece hangs in an underground chamber where men and boys as young as eight years old once toiled for 12 hours a day, six days a week, in semi-darkness.

The Welsh slate industry – which hit its production peak in the late 19th century – indelibly changed the landscape of north Wales and shaped the nature of its communities for generations.

The installation has been brought to Snowdonia by Bun Matthews, a local businesswoman who is passionate about landscape painting.
