Upnor Castle

Upnor Castle belongs to the genre of Henrician cosastal forts but is an Elizabethan addition to the chain. It was begun in 1599 to guard the approach to the new dockyard at Chatham, lying two miles away near the estuary of the River Medway. Sir Richard Lee interrupted his work on the fortifications at Berwick-on-Tweed, to come and design this fort, but construction dragged on for eight years.

In that year, the Dutch, under Admiral de Ruyter, sailed into the Medway and set fire to much of the English fleet. The castle was unable to offer any effective resistance and in the following year …

This is the tallest of the Norman keeps, rising 115 feet to the top of its corner turrets. Archbishop Corbeil’s keep is intact save for the loss of its roof and floors. A relatively small floor area accentuates the height; small that is when compared with an immense cuboid such as Dover. The keep is five stages high, including the double story, which contained the hall and solar. Originally, the only entrance was at first floor level via a fore building. The fore building is a tall and narrow projection, higher than …
