Porta San Frediano is one of the best-preserved gates in Florence's 14th-century city walls, built between 1332 and 1334 and unusual in retaining its original wooden doors — a rarity among medieval Italian city gates, where doors were typically replaced or destroyed over the centuries. The gate stands at the western end of Borgo San Frediano, where the street meets the surviving stretch of city wall.
The tower above the gate rises 24 metres and is faced in rough stone. It was one of the principal western entrances to the city and marks the boundary between the densely built Oltrarno and the former open ground beyond the walls. Today it is a useful orientation point for exploring the San Frediano neighbourhood: the artisan streets and working trattorias of Borgo San Frediano lie immediately behind it, while the Torre di Bellosguardo and the hills beyond are visible through the gate arch. The gate is not open to visitors inside, but the exterior is freely accessible.
