The Main Gate into Birgu (Vittoriosa)
says it all with the Latin inscription from Psalm 139 (140) which reads "Obumbrasti
super caput meum in die belli" which translates into "You will put a shade over my head in
the day of war". (Unfortunately the coat of arms underneath it in soft
limestone is no longer discernible, ostensibly at least in part because of
damage inflicted by the French during their relatively brief occupation.) The fortifications of Birgu fulfilled this
purpose of protecting its inhabitants during the Great Siege of 1565.

On the landward side Birgu has an
interesting complex of three gates in sequence: The Advanced Gate, the Couvre Porte, and
the Main Gate. Essentially these are set in turn within a 'ravelin' and
thence a bridge across the moat and finally to the main gate proper.
The land facing curtain walls are
characterised by two classical bastions
(St John and St James) each having its own cavalier (tower). In addition to
these there is the paired demi-bastion with intervening parapet (thus
comprising a 'hornwork') of the Post of Castille.
On the seaward side, the main
fortification is Fort St Angelo (the 'Castrum Maris' of ancient times) at
the tip of the promontory, besides which there are walls facing Kalkara. The
aspect that faces Senglea did not need correspondingly heavy
fortifications.
These two photographs taken from different angles show how Fort St Angelo
dominates the centre of the Grand Harbour.
The following image shows the Castellan's palace 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.
