Grosmont Castle, Monmouthshire

Grosmont Castle is a ruined Norman castle in Grosmont, Monmouthshire. The fortification was established by the Normans in the wake of the invasion of England in 1066, to protect the route from Wales to Hereford. It was originally an earthwork design with timber defences. In response to the Welsh revolt of 1135, King Stephen brought together Grosmont, Skenfrith and White castles to form a lordship known as the "Three Castles", which played a role in defending the region from Welsh attack for several centuries. King John gave the castle to Hubert de Burgh in 1201. Hubert rebuilt the castle in stone. Edmund, the Earl of Lancaster, gained possession of the castle in 1267, and it remained in the hands of the earldom and later Duchy of Lancaster until 1825. The castle was besieged in 1405 during the Glyndŵr Rising. By the 16th century it had fallen into disuse and ruin. It is in the care of Cadw. It is within the council area of Monmouthshire.
