Upnor Castle overlooks the River Medway and was built for the sole purpose of protecting the Royal Navy anchored further up the river.
On its one and only test if failed spectually resulting a disaster for King Charles II war plans, leading to a quick end to the war and a favourable peace for the Dutch. It was one of the worst defeats in the Royal Navy's history, and one of the worst suffered by the British military, described as the "most serious defeat it has ever had in its home waters."
The castle is a curious Elizabethan fort of an unusual design still intact with plenty to explore.
There is a car park nearby which is well sign posted with an enjoyable short walk down a cobbled street to the castle.
