Held at Clearwell Caves, Nr Coleford, Forest of Dean, Gloucestershire, GL16 8JR.

The strange beauty of an iron-age cave system is the backdrop for a mythic performance by the renowned Pentabus Theatre working with rising stars Kindle Theatre.

Playing for only three nights (11-13 July) in the subterranean depths of Clearwell Caves, Coleford, in the Forest of Dean, Underland melds drama, music, light – and darkness – to astonishing theatrical effect.

In Underland, ancient myths of love and loss are brought to life deep underground by a multi-talented company directed by Pentabus’ award-winning young director Orla O’Loughlin.

Says O’Loughlin: ‘Underland promises to be a thrilling and inspiring experience for audiences – all you need to bring is a warm jacket and a sense of adventure. The caverns transport you back through time, a place hacked out of the rock by human hands over thousands of years. Clearwell Caves have an incredible, elemental power which brings you face to face with the ancient mysteries - the underworld, creation, ideas of love and redemption. Our show is a celebration of those myths - light and darkness, laughter and loss, life and death.’
