When I first saw this castle I assumed that it had lost the upper part of its walls - but no, it may have lost its battlements but little else. It was never intended to be defended against infantry but only as a platform for cannon to defend against hostile ships and so did not need to be very high.

Rye can be seen on the horizon.

You can see here that the central tower, the keep, is higher than the surrounding walls. This castle was originally built at the end of a shingle spit with the sea virtually lapping against its walls.

It is now a long way from the sea.

This shows the central tower or Keep from near the main entrance.

There were four gun platforms linked by a curtain wall which had a defensive passage behind it and each of the outer towers had a passage linked to the central tower.

Near the outer wall looking past the Keep to the opposite part of the outer curtain wall.
