Dartmouth Castle is an artillery fort perched on the cliffs overlooking Dartmouth Harbour in Devon, England, guarding the narrow entrance to the Dart Estuary for over six centuries. Built beginning in the 1380s, it became home to the oldest known purpose-built coast artillery fort in Britain, with its distinctive gun tower begun around 1481. The castle's strategic location above a sheltered, deep-water port made it crucial for protecting the wealth of the town built on medieval trade routes. Visitors can explore the remains of this historic fortification, which saw action during the English Civil War and both world wars, now maintained by English Heritage.
