The twin drum towers of Westgate close off the western end of the High Street and are the most photographed view in Canterbury. The structure is the largest medieval city gate to survive anywhere in England — 60 feet high, with arrow slits, machicolations, and the original portcullis groove still visible inside.
A small museum occupies the upper floors with arms, armour, and a few exhibits on the gate's later life as a prison. Climb to the roof for the best view in the city — straight down the High Street to the cathedral, and out west over the Stour. The cafe in the adjacent gardens is a good place to plan the next move.
