The Agincourt muster
Though the historical record is somewhat incomplete, Tretower is thought to occupy an important place in the Agincourt story. Due to the destruction of the castle at nearby Crickhowell during the Welsh uprising under Owain Glyndŵr, Tretower Castle is likely to have been the muster point for the local contingents who responded to Henry V’s call to arms in 1415.
The castle and the manor
Tretower is an unusual ‘two-in-one’ historic site spanning many centuries. It incorporates the now ruined castle and later manor house, Tretower Court. This later building is a rare specimen, beautifully preserved and one of only a handful of its type to be found in Wales. It demonstrates the shift in architectural priorities from the 15th century onwards as the threat of conflict declined and fortified castles gave way to comfortable manor houses.
The Vaughan family
Tretower Court was owned by the influential Vaughan family and designed to reflect their high social status. Roger Vaughan of Bredwardine was married to Gwladys, daughter of local nobleman Dafydd Gam. Both Roger Vaughan and Dafydd Gam were said to have fought at the Battle and according to legend were knighted on the battlefield as they lay dying. A suite of rooms has been recreated as they may have been in 1470 when the Vaughans were movers and shakers in the high society of the times. The wall hanging in the Great Hall depicts a scene from Agincourt.
