About
Along with Skenfrith and White Castle, Grosmont Castle is one of the ‘Three Castles of Gwent’ built by the Normans to control a key section of troublesome border country. The original earth-and-timber stronghold, build on a gros mont (French for ‘big hill’), was later replaced in stone. It experienced an active life looking over the Monnow Valley on the Wales-England border. Thirteenth-century reconstruction included the gatehouse and circular towers. Remodelling a century later gave Grosmont apartments fit for a noble household, but by the 15th century the castle was in the wars again, besieged in the rebellion led by charismatic Welsh leader Owain Glyndwr. It then fell into ruin in the 16th century.
Nowadays the castle is open all year round and free to visit.
