When you reach Piazza Antenore, you can see the ancient Ponte San Lorenzo from a semi-transparent slab. It is the only one of the five ancient Roman bridges still visible and takes its name from the ancient Church of San Lorenzo, which stood here and was razed to the ground by Napoleon. Actually, the original name of this bridge until the 15th century was Ponte di Santo Stefano because of a neighbouring monastery. However, the bridge is a three-arched bridge over the river Brenta built between 40 and 30 B.C., which reached as far as Canton Gallo. In the central arch it is still possible to read the names of the four governors of the city at the time who initiated its construction.
