The Ponte Santa Trìnita is the oldest elliptic arch bridge in the world, characterised by three flattened ellipses.

[3] The wooden bridge of 1252 collapsed under the weight of a crowd seven years later, and was rebuilt in stone; this structure was in turn destroyed by a flood in 1269 and again in 1333.

Four ornamental statues of the Seasons were added to the bridge in 1608, as part of the wedding celebrations of Cosimo II de' Medici with Maria Magdalena of Austria: Spring by Pietro Francavilla, Summer and Autumn by Giovanni Caccini, and Winter by Taddeo Landini.

On the night between 3-4 August 1944, the bridge was destroyed by retreating German troops on the advance of the British 8th Army.

The bridge was reconstructed in 1958 with original stones raised from the Arno[4] or taken from the same quarry of Boboli gardens, under the direction of architect Riccardo Gizdulich, who examined Florentine archives, and engineer Emilio Brizzi.
