The bridge of San Lorenzo: photo description (Ponte San Lorenzo)

The bridge of San Lorenzo is a Roman arch bridge over the river Bacchiglione in Padua. Constructed between 47 and 30 BC, it is one of the first bridges of its type in the world. Also known by its slender pillars, unsurpassed in ancient times.

The Ponte San Lorenzo was one of four Roman bridges in ancient Padua, built over the river Bacchiglione (then known as Medicus). It is on the modern street of via San Francesco. Today, this three-arch bridge for the most part framed by buildings that for centuries were getting closer and closer to the banks of the river. Only the Eastern arch of the bridge was highly visible until the mid-20th century, but it disappeared when the channel was filled in and turned into the street Riviera del Ponti Romani. Intact bridge arches visible today on the street it is even possible to walk at certain times by prior arrangement.

Two other Roman bridges in Padua are closed for inspection: the Ponte corbo, also located on via San Francesco, and the completely inaccessible Ponte Altinate - via Altinate. Another ancient bridge Ponte San Matteo is close to the homonymous Church.

The bridge of San Lorenzo is of 53.3 meters in length, and 8.35 metres in width. Its date of construction is immortalized in inscriptions. The bridge is an important monument of ancient engineering art: its graceful arches have a length of from 12.5 to 14.4 metres. The thickness of pillars varies from one-half to one-fifth of the width of the span. Small size supports create less resistance to the flow of water, and thus reduce the risk of erosion of the base. Bridge design San Lorenzo could be reproduced only at the end of the middle Ages.
