The festival was first held in September 2015, following one of the festival’s Board members, Eleri Twynog, seeing a performance for children, based on the story of Henry Tudor, at Raglan Castle.
Cynhaliwyd yr ŵyl gyntaf ym mis Medi 2015 ar ôl i Eleri Twynog, aelod o Fwrdd yr ŵyl, weld sioe am Harri Tudur yn cael ei pherfformio, i gynulleidfa o blant oed cynradd,yng Nghastell Rhaglan.
