In 1735, the fort was reported as being in a good state of repair, but its artillery was reduced to 2 pieces of 24-gauge cannon and another 12 of various calibres that were out of service. Repair works were carried out in the middle of the same century, including the application of tiles in the small chapel. However, soon after work was completed the fort and chapel were severely damaged by the earthquake of November 1, 1755, although many of the tiles have survived. A decade later work was carried out to expand the structure, beginning with the so-called New Battery.
