Abergavenny Castle

Abergavenny Castle (Welsh: Castell y Fenni) is a ruined castle in the market town of Abergavenny, Monmouthshire, Wales, established by the Norman lord Hamelin de Balun c. 1087. It was the site of a massacre of Welsh noblemen in 1175, and was attacked during the early 15th-century Glyndŵr Rising. William Camden, the 16th-century antiquary, said that the castle "has been oftner stain'd with the infamy of treachery, than any other castle in Wales." It has been a Grade I listed building since 1952.
