The Triple Bridge, or Tromostovje in Slovenian, spans the Ljubljanica river in the heart of Ljubljana. This singular ensemble of three adjoining bridges connects the medieval old town to the modern city, and constitutes one of the most frequently crossed passages between Prešernov trg and Mestni trg. Its distinctiveness lies in the combination of a central stone bridge, dating from the nineteenth century, with two pedestrian walkways added in the 1930s by Slovenian architect Jože Plečnik.

Why visit the Triple Bridge

The Triple Bridge is a central landmark of Ljubljana, both a pedestrian crossroads and an architectural work. Three main reasons make a visit worthwhile:

• A rare architectural signature: few cities possess a system of three parallel bridges forming a single ensemble.
• A witness to the city's urban history, from the Middle Ages to Plečnik's modernist interventions.
• A privileged vantage point over the Ljubljanica, the baroque facades of the old town, and the castle perched in the background.

Access is free, and the site has been integrated into the city's pedestrian zone since 2007, making it a natural stop on any tour of the historic center.

History of the Tromostovje

The first written mention of a bridge at this location dates back to 1280, under the name Stari most (the old bridge). In the early fourteenth century, the structure is also referred to as the Bridge of Shoemakers and Špitalski most (Špital bridge), reflecting neighboring activities and institutions. Destroyed by fire, it was rebuilt in 1657.

In 1842, architect Giovanni Picco, originally from Villach (in Carinthia, then part of the Austrian Empire), replaced the lower bridge with a new structure featuring two arches and a metal railing. Named Frančev most (Franz Bridge) in honor of Archduke Franz Karl, it was inaugurated on September 25, 1842.

The decisive turning point came between 1929 and 1932, when Jože Plečnik, a major figure in Slovenian architecture, added two lateral pedestrian walkways to the central stone bridge. His objective was twofold: to prevent congestion at the crossing and to create a cohesive urban composition between Prešernov trg, the central square, and Mestni trg, the municipal square. Plečnik designed the central bridge in an arched form, while the two lateral walkways adopted a funnel-shaped path, visually widening the public space. Two staircases descend from the lateral bridges to the lower terrace arranged along the riverbank.

The Triple Bridge was renovated in 1992, then integrated into Ljubljana's pedestrian zone in 2007.

What to see on site

Plečnik's architecture

The lateral walkways are characteristic of Plečnik's vocabulary: artificial concrete balustrades featuring approximately 642 balusters, spherical streetlights, and descent stairs toward the banks. The central bridge retains some of its Glinica limestone, complemented by concrete in subsequent repairs.

The platform and surroundings

Previously covered with asphalt, the platform was repaved in granite blocks in 2010, which unified the appearance of all three bridges. On either side, the cafe terraces of Prešernov trg and the facades of the old town provide a photogenic setting, particularly in the late afternoon.

Immediate connections

To the north, the bridge opens onto Prešernov trg, dominated by the pink Franciscan church. To the south, you reach Mestni trg and the Saint Nicholas Cathedral, as well as the central market, also designed by Plečnik.
