Description:A view of the Eastern Front of Warwick Castle.
In the foreground are the Gatehouse and Barbican. Caesar's Tower, shaped like a clover leaf, is to the left. Its design allowed more defensive troops to gather along its machicolations (the additional walkway two thirds of the way up) in order to defend the gatehouse. Beneath lie the dungeons.
In front of the buildings is a small bridge. Running beneath is a moat, although water has never flowed through it. The moat is simply a ditch.
Behind Caesar's Tower is a drop of around a hundred feet to the River Avon. This explains the difficulty in filling the moat, not least in the fourteenth century when these parts of the castle were built.
