People in Caerphilly awoke to find the mythical Welsh dragon bursting from the town's castle banks on St David's Day.

The four-metre (13ft) long attraction, with black and red scales and smoke-flaring nostrils, was created by Cardiff-based prop design company, Wild Creations.

It marked the launch of a campaign by Wales' historical heritage body, Cadw, to bring to life never-seen-before events at its sites.

Deputy Minister for Culture, Sport and Tourism, Ken Skates, said: "Dragons feature in many of Wales' great myths and legends and it is stories like these that make our country's heritage so unique."

A time-lapse video showed the dragon being made by Wild Creations - the firm that embedded a giant rugby ball in Cardiff Castle's walls during last year's Rugby World Cup.
