TINTERN Abbey has seen the unannounced appearance of giant mirrored letters spelling ’EPIC’ within its grounds.

Since Thursday the artwork has provided the perfect backdrop for selfies as Visit Wales steam ahead with its campaign to promote Wales as an adventure destination.

The letters, reaching four metres high and 11 metres wide, have been stopping off at different locations across Wales over the summer.

Fiona Wilton, vice chair of Wye Valley and Forest of Dean Tourism Association, said: "Guests in the Wye Valley have such a choice of wonderful adventures and are enjoying them immensely. Right now everyone is taking to two wheels as we are all thrilled by the success of the Welsh cyclists in Rio. On September 8 the mighty Tour of Britain comes through Tintern and locals and guests alike are sure it will be Epic indeed."

The installation took three weeks and four people to build, and each letter weighs a staggering 350kg.

Visitors are encouraged to share their pictures on social media using the campaign hashtag #FindYourEpic.

The letters are there until next Thursday (August 25).
