The Ponte Santa Trìnita (Italian for Holy Trinity Bridge, named for the ancient church in the nearest stretch of via de' Tornabuoni) 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 (95 ft) with the centre span being 32 m (105 ft) in length. The two neighbouring bridges are the Ponte Vecchio, to the east, and the Ponte alla Carraia to the west.
