Ponte Santa Trinita


The Ponte Santa Trìnita is a Renaissance bridge in Florence, Italy, spanning the Arno. The Ponte Santa Trìnita is the oldest elliptic arch bridge in the world, characterised by three flattened ellipses. The outside spans each measure 29 m with the centre span being 32 m in length. The two neighbouring bridges are the Ponte Vecchio, to the east, and the Ponte alla Carraia to the west.
The bridge was constructed by the Florentine architect Bartolomeo Ammannati from 1567 to 1569. Its site, downstream of the Ponte Vecchio, is a major link in the medieval street plan of Florence, which has been bridged at this site since the 13th century. The wooden bridge of 1252 was swept away in a flood seven years later and was rebuilt in stone; this structure was in turn destroyed by a flood in 1333. The bridge of five arches constructed by Taddeo Gaddi was also destroyed in the flood of 1557, which occasioned Ammannati's replacement. 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 and 4 of August 1944, the bridge was destroyed by retreating German troops on the advance of the British 8th Army. A Bailey bridge was built for temporary use by the Royal engineers. The bridge was reconstructed in 1958 with original stones raised from the Arno or taken from the same quarry, under the direction of architect Riccardo Gizdulich and engineer Emilio Brizzi. The missing head of Primavera was recovered from the bed of the Arno in October 1961.
