Llanasa is village in the county of Flintshire, north-east Wales. Llanasa is described as one of the ancient parishes of Flintshire. It originally comprised the townships of Gronant, Gwespyr, Kelston, Golden Grove, Picton, Trewaelod, Axtyn and Trelogan.
Named after Saint Asaph the village is known to have existed since at least c.600 AD and was originally called Llanasaph meaning the Church of Saint Asaph. It was where the tomb and relics of Saint Asaph were enshrined before they were moved to the larger St Asaph Cathedral sometime before 1281. This ancient parish church was later the burial place of Gruffudd Fychan (the father of Owain Glyndŵr). The stone slab which covered his tomb survives and is engraved with the words HIC LACET GRVFVD VACHAN or "here lies Gruffudd Fychan". This slab, according to records, was originally in the centre of the south aisle and it would appear that Gruffudd Fychan was buried somewhere in this church sometime between 1350 and 1370. His mortal remains have not been found.
Welsh relatives of Glyndŵr, known as the Hughes of Gwerclas family, continued to live in the area during the 18th and 19th centuries.
Elis Gruffydd, the 'Soldier of Calais', was born at Gronant Uchaf in this parish. He travelled to Calais first with Sir Robert Wingfield in 1520. Returning after a spell in London, he completed in around 1522 his massive world history, 'Cronicl Oes y Byd', telling of the Six Ages, and specifically the histories of Wales and England. The work is now contained in two manuscripts at the National Library of Wales.
