The Triple Bridge (Tromostovje) is an iconic group of three bridges spanning the Ljubljanica River, connecting the medieval old town with the central Preseren Square. Dating back to the 13th century in its original wooden form, the central stone bridge was built in 1842. In 1929-1932, the renowned Slovenian architect Joze Plecnik added two side pedestrian bridges at a slight angle, creating the unique triple formation seen today. The bridge was added to the UNESCO World Heritage List in 2021 as part of Plecniks Ljubljana. Since 2007, all three bridges are pedestrian-only.
