Castello a Mare

Castello a Mare is an archaeological site in Palermo, Italy, guarding the entrance to the Cala harbour. Its fortress began in the tenth century under Arab rule. A central mastio stood inside a trapezoidal enclosure, while open ground separated the stronghold from Palermo. Norman rulers later strengthened the citadel with further defensive works. In 1496, Ferdinand the Catholic’s reign brought two entrance towers, a central archway, and a royal coat of arms.

In 1535, Don Ferrante Gonzaga added bastions and moats, making the complex Palermo’s principal stronghold within new walls. Two city-facing bastions bore the names Saint Peter and Saint Pasquale. The enclosure also contained a parish church, prisons, and a viceroy’s residence in 1517. Garibaldi ordered its demolition in 1860, and dismantling ended in 1922 for a trapezoidal port pier. Archaeological excavations exposed part of the entrance tower, a circular tower, and western moats. These fragments preserve the fortress’s changing Arab, Norman, and Spanish layers beside Palermo’s port.
