Fortificazioni di Cagliari

Cagliari's fortifications form a layered defensive system around the Castello hill. Pisan towers, Spanish-era bastions and later Savoy works reflect the city's changing military role from the medieval period into the modern age.

Why it matters

The surviving walls and towers trace several centuries of military engineering. Pisan rulers built towers around the hill; later, Spanish engineers adapted defences to artillery. Parts of the system were rebuilt or removed after Cagliari ceased to function as a fortress in the nineteenth century. The Bastione di Saint Remy now provides a monumental link between Castello and Villanova.

What to notice

The Torre dello Sperone, also known as degli Alberti, dates to 1293. The Torre di San Pancrazio followed in 1305, and the Torre dell'Elefante in 1307; both were designed by Giovanni Capula. A small marble elephant on the latter gives the tower its name. The Bastione di Santa Croce was begun under viceroy Dusay and later given a pentagonal form by Jacopo Fratino. Saint Remy rises over the former Sperone and Zecca bulwarks, with ramps leading to the Umberto I terrace.

Context and history

Pisan fortification of Castello expanded in the late thirteenth and early fourteenth centuries. In the sixteenth century, the engineer Rocco Capellino developed a bastioned perimeter, including works around San Pancrazio and the harbour. Later Savoy interventions brought new walls and bastions, and the royal arsenal was established in 1727 on the site now occupied by the Cittadella dei Musei. As Cagliari's military role receded, sections of the fortifications were removed, while the surviving towers became lasting landmarks of the city.
