The Motte was probably built by the Norman Lord Hamelin de Ballon in 1087 AD. The tower built at the top of the motte would have been wooden. Beneath the motte was the bailey - a courtyard containing the outbuildings and stables.
The whole castle was destroyed in 1233 by Richard Marshal, Earl of Pembroke, and the Welsh princes. The keep was rebuilt in stone.
The first Great Hall in the castle was probably a timber building. Within this Hall, on Christmas Day 1175, the Norman Lord of Abergavenny, William de Braose, murdered his long-standing Welsh rival Seisyll ap Dyfnwal.
In 1182, the castle was attacked by relatives of the murdered Welshmen. Most of William's men were captured, but he was not at home. The walls you see today are the remains of a stone Hall built between 1233 and 1295. Tags: Abergavenny Museum
