Upnor Castle
About
Upnor Castle is a rare Elizabethan artillery fort that proudly guards the River Medway on the western bank of Kent. Built between 1559 and 1567 under the orders of Queen Elizabeth I, the fortress was designed to protect the Royal Navy’s Chatham Dockyard and the ships anchored on the Medway. Though it suffered a brief but notable raid by the Dutch navy in 1667, the castle survived and later served as the region’s primary ammunition depot until the late 19th century. Today, English Heritage manages the site as a public museum, offering visitors a glimpse into England’s maritime history through its well‑preserved walls, the iconic water bastion, and a collection of period weaponry and exhibits. The visitor experience blends history and atmosphere: a guided audio tour explains the fort’s key features, while open‑air theatre and summer re‑enactments bring the 17th‑century story to life. The castle’s two‑storeyed rectangular block, surrounding curtain wall, and the remaining gatehouse’s crenellated design are all remarkable for their original architecture. For history enthusiasts and photography lovers alike, the winding courtyard and the magnificent view across the Medway make Upnor Castle a must‑visit landmark. Whether you’re intrigued by early modern warfare, visiting a cool riverside village, or simply looking for a unique day out in Kent, Upnor Castle offers a quiet, immersive experience that links the past with the present.
