With a sight on San Pietro Castle, Ponte Nuovo ("New Bridge") has been such several times. Built, repaired, destroyed and built again endless times - floods, fires various accidents - since the 12th century, it came to a fixed point in 1539, but it went down due to a broken millwheel carried in the overflow three centuries later. It was replaced by a new single-span, iron structure soon nicknamed "bird cage" due to its appearance. It did not event get to the 20th Century, since it was rebuilt in iron on pillars as a way (as it already was) to cross the river for trams (publc transport active since 1884 by horse, electrical from 1906 and abandoned in the mid-fifties). However, its shape was further changed in the Thirties, since it was not fit to the city needs, but as soon as six years later, on April 25, 1945, it was blown up by the Germans falling back. A quick reconstruction, more practical than aesthetic, gave the city its last (by now) Ponte Nuovo.
