What is recorded here
Hamelin de Ballon raised timber walls on the old Roman fort around 1087, beginning a lineage marked by blood and fire. William de Braose later lured Seisyll ap Dyfnwal into the great hall under a false promise of peace, then killed every guest before fleeing the retaliation that followed. The castle survived Owain Glyndŵr’s siege with a heavy garrison, stood through changing lords, and finally lost its keep when royal or parliamentary orders called for demolition during the English Civil War. What remains is a mound, a gatehouse, and the shape of repeated violence made flesh in stone.
The National Monuments Record of Wales records Abergavenny Castle as Castle from the Medieval period. The saved point comes from the official national record. Inclusion does not by itself mean that the public may enter the place.
Abergavenny Castle was built by the Normans in the 12th century and later held by the powerful de Clare family. It is important as a key example of medieval military architecture and as a historical center in the strategic Marches region between England and Wales.
