One of the most beautiful, but not extremely well-known buildings in Ljubljana is the almost surreally colourful Cooperative Commercial Bank. Designed in 1921 by the Slovenian architect Ivan Vurnik and completed the following year, the building's unmistakable façade was actually painted by his wife Helena, herself a Vienna-born artist. While the building is squarely rooted in the Secessionist movement, it also must be considered one of the finest examples of Slovene national style architecture as the façade and interior wall paintings present a stylised interpretation of traditional Slovene iconography.
