Fortezza Firmafede (the Citadel)
The large square fortress with round towers closes the southern side of the old town. Lorenzo de’ Medici had it built between 1487 and 1492, after Florence defeated Genoa, on the ruins of a 13th-century Pisan stronghold called Firmafede. In the 19th century it became a barracks and then a prison until the 1970s; restoration reopened it in 2003.
Today you visit the parade ground, the towers, the wall walk, the tunnels and the cells; in summer it hosts exhibitions and the national antiques fair. A full ticket costs €5, a combined ticket with Sarzanello €8. In October 2026 it opens Tuesday to Sunday in the morning, plus weekend afternoons: check the Fortezza Firmafede website. History, tickets and tips for seeing both are in our guide to the fortresses of Sarzana.
