Upnor Castle, Tudor artillery fort in Frindsbury Extra, United Kingdom.
The two-story stone and brick fortress extends along the western bank of River Medway with a triangular gun platform facing the water.
Built between 1559 and 1567 under Elizabeth I's orders, the castle served to protect Chatham Dockyard from potential naval attacks during tensions with Spain.
The castle exhibits military engineering of the Tudor period through its gun emplacements, defensive walls, and strategic riverbank positioning for artillery deployment.
The castle functions as a museum with exhibits displaying military artifacts, offering guided tours and educational programs about Tudor naval defense systems.
During the Dutch Raid of 1667, the castle's garrison maintained effective defense of the Medway, preventing the complete destruction of naval facilities upstream.
