To provide a safe place of retreat in case of similar attacks in future it was resolved to erect a keep or castle on a promontory of rock which juts out into the sea at the south side of the island.

To the east a small projection or tower contained on the first floor the lavatory and latrines, and at the top was carried up as a watch-tower above the parapet, and
