Dover Castle

Dover Castle is a medieval castle in Dover, Kent, England. It was founded in the 11th century and has been described as the "Key to England" due to its defensive significance throughout history. It is the largest castle in England.
This site may have been fortified with earthworks in the Iron Age or earlier, before the Romans invaded in AD43. This is suggested on the basis of the unusual pattern of the earthworks which does not seem to be a perfect fit for the medieval castle. Excavations have provided evidence of Iron Age occupation within the locality of the castle, but it is not certain whether this is associated with the hillfort. The site also contained one of Dover's two 80-foot Roman lighthouses , one of which still survives, whilst the remains of the other are located on the opposing Western Heights, across the town of Dover.
