worked on repairing the damage and improving the fortifications, strengthening the flanks and constructing a new artillery platform. In 1678 it frustrated the attack of a French squadron and in 1680 fought off another attack by 800 men led by Franquesma, the second-in-command of the Antilles filibusters. Between 1675 and 1692 the fortress was damaged by a series of earthquakes and reconstruction had to be carried out under the direction of Francisco Pérez between 1693 and 1695. From 1738–1740 further work was undertaken by the engineer Antonio de Arredondo, who enlarged the citadel and completed some of the unfinished platforms, with Juan Martín Cermeño and Francisco Calderín making the final changes to the structure after it was again damaged by earthquakes between 1757 and 1766. By 1775, the fear of attack had diminished, and the parts of fortress known as the Rock (la Roca) and the Star (la Estrella) were converted into a prison for political prisoners, although the rest of the fortress continued to serve as a military base. It was again used as a fortress in 1898 when the United States' fleet attacked Santiago de Cuba during the Spanish–American War. During the 20th century the fort fell into disrepair, but it was restored during the 1960s by Francisco Prat Puig.
