North Flank Casemates

During a new fear of invasion from Napoleon III two new dry moats were added to the existing citadel defences. The northern and the southern moat both had their own casemates built. Between these, there was also a defensive caponier built, but sadly this was filled in during the 1960s by the Dover Corporation and they gradually destroyed many parts of the Western Heights.

The northern casemates are a lot larger than the southern casemates, with six separate rooms whereas the southern casemates had eight.
