Castell Rhaglan is a late medieval castle situated in Monmouthshire, Wales, which was begun in 1431 by William ap Thomas and substantially developed during the fifteenth and sixteenth centuries. The castle is distinguished by its impressive hexagonal tower, known as the Yellow Tower of Gwent, which was constructed as the focal point of an outer ward surrounded by its own moat, creating a formidable gatehouse structure. The main castle comprises a rectangular inner ward with corner towers and residential ranges, reflecting the castle's dual purpose as both a military stronghold and a seigneurial residence of considerable status. Castell Rhaglan remained an important fortification and noble seat until it was partially slighted after the English Civil War, yet substantial portions of its medieval fabric survive, including much of the curtain walls, towers, and the distinctive tower gateway that represent significant examples of late medieval military architecture in Wales.
