The following image shows the Castellan's palace i the uppermost level within Fort St Angelo. It still has features betraying its Siculo-Norman origin. The rim of the well head is fashioned out of the neck of a large old Roman amphora.
Fort St Angelo distinguished itself in the Great Siege of Malta in 1565, when it held out against repeated Ottoman assaults. It last saw active military service in World War II when its ramparts hosted Bofors light anti aircraft guns, initially manned by Royal Marines and later by the Royal Malta Artillery.
