White Castle is a concentric castle situated in Monmouth, Gwent, Wales, constructed during the late 12th and 13th centuries. The fortress was built as part of the Norman defensive network in the Marches and is notable for its distinctive white-rendered stonework, which gives the castle its name. The castle exemplifies concentric military architecture, featuring an inner ward surrounded by a strong outer curtain wall, multiple towers, and a substantial moat, reflecting contemporary developments in medieval fortification design. Cadw, the Welsh heritage organisation, maintains the site as a monument of considerable archaeological and architectural importance.
