Overview

History & significance

Upnor Castle is a Tudor artillery fort built between 1561 and 1567 on the Medway estuary in Kent to protect English naval vessels and the royal dockyard at Chatham. The castle features the characteristic low, angular bastioned design typical of mid-sixteenth-century coastal defences, constructed to withstand cannon fire rather than to mount offensive artillery in significant numbers. Built under the direction of military engineer Richard Watts, the fort comprises a central keep surrounded by angled bastions and defensive walls, and originally included gun emplacements and accommodation for a garrison. The castle gained historical prominence during the Medway Raid of 1667, when Dutch naval forces attacked English shipping on the river, and the fort's subsequent upgrading demonstrated the continued strategic importance of protecting the Medway approaches and the growing naval complex at Chatham.
