ZTL Siena
Siena’s restricted zone is effectively the entire walled city, and enforcement is continuous rather than confined to working hours. But the cameras are not at the medieval gates, which is the assumption that catches people: several approach roads run inland from a gate to a camera set back inside the walls, and that stretch is precisely how you legally reach a car park. The boundary is the camera line, not the masonry. Beyond it there is almost nothing worth driving to even if you were permitted — the centre is a network of steep, narrow, largely pedestrian lanes converging on the Campo.

ZTL Siena
Daily, 24 h
One of Italy's oldest ZTLs. Covers the walled centre except a few approach corridors running inland to a camera gate. Two stricter sub-zones sit inside it — 'Zona A' and the 'Y storica', enlarged in April 2025 to take in Piazza del Campo, Salicotto, Porrione and Salimbeni — both officially 'a prevalenza pedonale'.
The ring of car parks below the walls
A series of paid car parks sits around the outside of the walls, each feeding a different gate. San Francesco on the northern side and Santa Caterina below the Fontebranda district on the west are the two visitors use most. Both are large, both are signed from the approach roads, and both are outside the zone.
Charges are modest by the hour with a daily cap, and there is cheaper and free parking further out for anyone willing to walk — with a bus into the centre from the outer areas.
Around the Palio the calculation changes entirely, and not merely because things fill up. For roughly two weeks before each race and a week after, streets close on a rolling schedule as the stands go up and the tufo is laid; parking is suspended and towed in places rather than simply full; and on race day the centre is under a general driving ban for most of the day. The Palio does not relax the ZTL — it adds restrictions on top. If you are arriving near 2 July or 16 August, check the Comune’s traffic bulletin first and expect the approach to your booked car park to have changed.
The escalators are the whole point
What makes the Siena car parks work is that several are connected to the centre by escalators cut up through the hillside. From San Francesco and from Santa Caterina a bank of escalators carries you up the steep part of the climb and delivers you into the historic centre near the top.
This matters more than it sounds. Siena is built along three ridges and the gradient between the car parks and the Campo is punishing on a hot afternoon. The escalators turn a hard twenty-minute climb into an easy ten-minute walk, and they are the reason the city can reasonably ask everyone to park outside.
The garages near the centre
Two garages named for the places they serve sit closer in and can be reached without crossing a camera gate if you follow the signed route. They are smaller and dearer than the outer lots, and the signed approach genuinely matters — improvising a way to them on a sat-nav is exactly how people end up passing a varco. If you use them, follow the brown parking signs from the ring road rather than the shortest line on a map.
Staying inside the walls
Hotels within the zone can arrange access for guests to reach the property and unload, and Sienese hotels are practised at it — but the streets are genuinely narrow and some addresses cannot be reached by car at all, whatever the permission says. Ask the property not only whether it can register your plate but whether it is physically possible to drive to the door, and where you should leave the car afterwards. The answer is usually one of the car parks outside the walls.
