The Cow Tower is a circular stone artillery tower located in Norwich, Norfolk, dating to the late fourteenth century. Built circa 1378-1385, it represents one of the earliest purpose-built artillery fortifications in England, constructed to defend the river crossing and city against raids during the Hundred Years War. The tower is constructed of flint and stone with a substantial circular plan, designed to mount small cannon on its gun platforms. This early defensive structure marks an important transition in English military architecture, demonstrating the adoption of gunpowder weaponry in civic fortification during the medieval period.
