San Gallo Gate, Medieval city gate in Piazza della Libertà, Florence, Italy.
San Gallo Gate stands in Piazza della Libertà and is one of the few remaining medieval city gates on the northern edge of Florence. Built in stone with Gothic features, it has a wide central arch flanked by two narrower side passages for pedestrians.
Work on the gate began in 1284 under Arnolfo di Cambio and was finished in 1327, opening the northern road toward Bologna. It was part of a ring of walls that enclosed the city during the medieval period.
Inside the gate, traces of a fresco showing Mary and saints are still visible on the walls, and marble plaques on the outside mark royal visits to Florence. The gate served not just as a passage but as a formal stage for public ceremonies.
The gate sits at the northern edge of the old city and is easy to reach on foot from the historic center. From here, a walk along the surviving sections of the old city walls gives a good sense of how the fortifications once surrounded Florence.
The architect Giuliano da Sangallo took his name from the convent he designed just outside this gate, not from the gate itself. The road leading through the gate gave the convent its name, and that name then stuck to the architect.
