A little history of Calvi citadel
Old Pisa's possession conquered by the Genovese in 13th century, Calvi housed in Antiquity a fortified sitting, rebuilt in 1268 by Giovanniello de Loreto.
Fortifications were designed by Milanese Cristoforo Gandino, who reinforced the Salt tower and the governor's palace. One century later, they put up tower de la Moza and tower of the Castellana, between 1483 and 1492.
Unfortunately, the citadel was destroyed in a gunpowder store's explosion in 1567. Then... Corsicans wanted their independence!
