[2] The present building was built in 1896, during the administration of Mayor Ivan Hribar, whose ambition was to transform Ljubljana into a representative capital of all the Slovene Lands.

In the early 1990s, an extension to the main building was built by the Slovene architect Edvard Ravnikar.

[5] In 2001, a large transparent glass gallery, designed by the Sadar + Vuga architecture bureau, was built to connect the two wings of the building.

The gallery hosts a permanent art collection from the Middle Ages to the early 20th century.

The original of the Baroque Robba fountain can also be seen in the central glass gallery of the building, where it was moved after extensive restoration in 2008.
