This was Glyndŵr’s headquarters - where his parliament was once
held and from where his alliance with France was forged. This
alliance was not only aligned to military aid but also involved
negotiations with Pope Benedict III to establish an archdiocese in
Wales independent of Canterbury. It was where his dreams of two
universities – one in the south and one in the north were
formulated.
Even with the fall of the castle to the forces of Henry IV in 1408,
Glyndŵr continued his guerrilla resistance over the next five years.
In 1415 he refused an offer of pardon from Henry V and is
believed to have lived out his life in quiet seclusion with his
daughter and her husband – an Englishman.
In 1647 the Castle was the last royalist defence to fall to
Cromwell’s Parliamentary forces in the Civil War against King
Charles I.
