The keep
is all that remains of the castle, which was built c.1207-12 in the reign
of King John. It is the only octagonal keep in England. It is almost
wholly of flint although some diagonal brickwork and stone is visible in
the last picture. Thin buttresses. Three stories high, clear in picture
from west.
