A short film commemorating a Welsh army victory in Wrexham more than 800 years is being premiered at Wrexham Histories Festival (4-5 February) at Glyndwr University.
The film highlights the battle of Crogen which saw Owain Gwynedd, a prince who ruled over a large part of north Wales, defeat the forces of Henry II in 1165.
The battle took place near what is now known as Castle Mill in the Ceiriog Valley with filming at local places, including Corwen hillfort Caer Drewyn and Vallé Crucis Abbey, Llangollen.
Commissioned by Wrexham Museum for a new display, filming brought together local historians, re-enactors and has been made by Chester-based CGI specialists Take 27.
The idea for the film came from local historians Deryn Poppitt and Mark Williams, both from Chirk, who have campaigned for years for the site of the battle of Crogen to get official recognition.
The script was produced by Julian Baum from Take 27 and Mark Williams, from his research from sources ranging from ancient Welsh documents to Victorian historical journals.
The story is narrated by a central character, Ynyr ap Hywel, played by local re-enactor Wyn Evans, described as "the hero of the Crogen" in early sources.
Re-enactment groups which took part were the Age of the Princes, Cwmwd Ial, House of the Black Star, Les Miles des Marches, and Samhain Welsh Medieval Society.
