The Battle of Bryn Glas (1402) was fought between the forces of Owain Glyndŵr and Sir Edmund Mortimer. The Welsh had raided deep into the latter's territory and the English followed in hot pursuit but were decisively defeated when Glyndŵr's men turned to fight. Mortimer was captured and later changed sides contributing to the destabilisation of Henry IV's regime.
The battle was fought on 22 June 1402 on a hill near modern Pilleth near the English/Welsh border. Although dispute rages about the extent of the battlefield, the centre of the fighting is securely placed around St Mary's church as evidenced by the discovery of significant numbers of grave pits.
Visiting the site can be included as part of the Grand 8 day tour of Wales.
