This is one of my favourite buildings of Verona, Ponte di Castelvecchio, also known as Ponte Scaligero.
It was built in three years, most likely in 1354-1356, by Cangrande II della Scala (hence the name Scaligero) to grant him a safe way of escape from the annexed castle in the event of a rebellion of the population against his tyrannic rule. The bridge was totally destroyed by the retreating German troops on April 25, 1945. A faithful reconstruction begun in 1949 and was finished in 1951.
I like the three arches and their different size. I often pass on this bridge coming from the town centre (on the right) to take my daughter to a little park that's just at the other side of the bridge.
