The Spanish Walls
The construction of the imposing walls and of the two adjacent bastions was
ordered in April 1529 by the viceroy of the Kingdom of Sicily, Ettore
Pignatelli, who planned the works down to the last detail. The building of the round
bastion of S. Maria was entrusted to the master builder Simone Messina, who was
also required to raise half of the long wall using 9 skilled workers and 22 labourers.
The master builder Carlo Florio, with the same number of workers, was to build the
other half of the wall and the imposing bastion of the islands.
All building works, including the parts of the wall that led from the two
bastions to the foundry and to the church of the Annunziata, were planned by
the military engineer Pietro Antonio Tomasello from Padova, who had been in the
service of Emperor Charles V since 1523.

the Bastion of S. Maria. In the background, the Bastion of the Islands, with
the Ravelin of S. Giovanni, built in the seventeenth century, in the centre.
A document from the 12th of
October 1529 reports that works had begun, slowly but surely, with
excavations for the foundations for the two bastions having been completed, but
without the foundations in place there was a very real risk that the ditches
could fill with water. On the other hand the construction of the foundations of
a portion of the wall between the two bastions had begun. By February 1532, a
third of the wall had been completed (80 of the 240 metres).
Alongside the men working
under the master builders Messina and Florio, a further 24 labourers were
employed for the construction of the foundations. 4 master engravers were also
brought in to sculpt the decorations in stone including
the robust stone cord around the lower part of each of the 55 oblique
ducts (“murder-holes”) used to bombard the enemy with stones that shot out
through the bottom.
Work was completed in around 1537. A century later, two advanced
fortifications (“ravelins”) were built to reinforce the defence of the wall
that was already protected by a dry ditch (with a drawbridge) and by the cannons
of the two adjacent bastions.
