The gate you see when you enter the ancient city of Siena is similar to the city gate. There is a sense of history, but no specific introduction was found. The first thing you see after entering the city gate is the University of Siena. The long passage leads directly to the Siena Cathedral.
This door is not far from the ZTL area, so you need to be careful when driving. There is a parking space at the door, 1.5 Euros per hour, 2 Euros for the second hour
