Dating back to the 13th century, it stands as the oldest bridge in Ljubljana.

In August 2021, the Triple Bridge was added to the UNESCO World Heritage List as part of Plečnik's enduring legacy.

It was also named the Špital Bridge (Špitalski most) after the nearby poorhouse, which was established in the early 14th century.

The essentials of the bridge have been preserved until today, which is evidenced by the inscribed dedication to the archduke above its central pier, reading in Latin "ARCHIDVCI.

"[4][5] In order to prevent the 1842 stone arch bridge from being a bottleneck, the architect Jože Plečnik designed in 1929 the extension of the bridge with two footbridges at a slight angle on each side of it.

In collaboration with his student Ciril Tavčar, who drew the plans, he published the proposal in the same year in the journal Ljubljanski zvon.
