A ruined castle.
Grosmont Castle is a ruined castle in the village of Grosmont, Monmouthshire, Wales. 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. Possibly commissioned by William FitzOsbern, 1st Earl of Hereford, it was originally an earthwork design with timber defences. In 1135, a major Welsh revolt took place, and in response King Stephen brought together Grosmont Castle and its sister fortifications of Skenfrith and White Castle to form a lordship known as the "Three Castles", which continued to play a role in defending the region from Welsh attack for several centuries.

One of the best preserved of 3 castles near the Dyke south-east of Llanvetherine. Under 16s must be accompanied by an adult.
A ruined former Augustinian priory.
The castle dates back to 1087; it was damaged in the 1404 Glyndŵr rebellion and abandoned. Just to be on the safe side, in 1645 Charles I had the remains "slighted" - demolished beyond further use. Later visitors found the ruins picturesque and in 1819 a hunting lodge was built within, in the style of a miniature "keep". This now contains the museum.
