St Briavels Castle is a moated Norman castle at St Briavels in the English county of Gloucestershire. The castle is noted for its huge Edwardian gatehouse that guards the entrance.
St Briavels Castle was originally built between 1075 and 1129 as a royal administrative centre for the Forest of Dean. During the 13th century the castle became first a favourite hunting lodge of King John, and then the primary centre in England for the manufacture of arrows for use with the longbow, the predominant missile weapon of the English in the later medieval period, and quarrels, large numbers of which were required for crossbows in medieval warfare.
