Triple Bridge, Stone arch bridge in Ljubljana, Slovenia

The Triple Bridge is a complex of three bridges over the Ljubljanica River: a central stone arch bridge built in 1842 from Glinica limestone, flanked by two concrete footbridges added by Jože Plečnik in 1932. All three have concrete balustrades with 642 balusters, and the platform is paved with granite blocks laid in 2010. The side bridges are slightly angled and lead to staircases down to the riverbank.

A wooden bridge stood here by 1280, later called the Old Bridge and Lower Bridge. After a fire in 1657 it was rebuilt, and in 1842 Giovanni Picco designed a two-arch stone bridge named Franz's Bridge, opened on 25 September 1842. Jože Plečnik added two concrete footbridges in 1929–1932, opened in April 1932.

The name Tromostovje, "three bridges", dates from Plečnik's 1931–32 addition of two concrete footbridges beside the 1842 stone bridge. The crossing lies where Ljubljana's two urban axes meet: the river axis and the transverse line from Ljubljana Castle to Rožnik. A crucifix once stood mid-bridge to protect it; removed in 1796, it is kept at the top of the steps before the Franciscan church.

Since 2007 the whole complex has been closed to motor traffic, so you cross on foot; before then trams ran over the central span until 1958, later buses 2, 10, 11, 13 and 20. A staircase beside the third footbridge leads down to the lower terrace of the Ljubljanica embankment. The granite paving dates from 2010.

The two side pedestrian sections are slightly different in height and angle from the central arch, offering varied viewpoints of the river and old town as you cross. This subtle asymmetry means each path reveals different aspects of Ljubljana when you walk across.
