Da Vinci has his Mona Lisa, Otto Wagner has his…well, many buildings in Vienna might be considered a highlight of the architect’s legacy. But the Postsparkasse building perhaps marks a turning point in modern architecture.
- Notable marble and aluminium façade
- Opened in 1906 with further expansion completed in 1912
- Perfect combination of aesthetics and utility
- Began as home to the state savings bank; now houses academic institutions

Postal Savings Bank building

(View from the front)
One of the more unique buildings in Vienna bears the name Österreichische Postsparkasse, which translates directly to the Austrian Postal Savings Bank.
This turns out to be a remarkably accurate description of the building’s original occupants. Though back at the time of construction, this was the imperial and royal version of the institution.
The Postsparkasse’s fame stems from the its role as a standout example of architecture from the era of Viennese Modernism, as a toned-down child of Viennese Jugendstil, and as a product of the great architect, Otto Wagner.
Wagner was chosen from among the 37 architects striving for the design contract. Construction work began on July 12, 1904 and the bank’s new premises opened in December 1906 (with additions in a second building phase that lasted from 1910-1912).
The architect’s creative hand guided all parts of the building, even down to the furniture and fittings. On the outside, marble plates and (decorative) aluminium rivets create the rather apt impression of a lockbox.
The combination of materials – notably aluminium, marble, glass and iron – would last “14 days longer than eternity” according to Wagner (as quoted in a newspaper article of the time).
Inside, a huge atrium-like hall with glass floor makes the best use of natural light:

Die Zeit described the Postsparkasse as a work of genius, noting that Wagner wanted to produce a building that was:
…a symphony in white, black, and grey, but particularly one guided by expediency. Light, air and intelligent use of space…everything that was missing from the old premises should be here in abundance.
As such, the Savings Bank represented Wagner’s desire to combine aesthetics with practicality – a core tenet of his modernist approach. As the Deutsches Volksblatt reporter wrote after a tour prior to the official opening:
The total impression given by the building must simply be described as beautiful and harmonious. Wagner has rarely managed to combine material and architectonics, stylish decoration (right down to the fine detail) and eminent fitness for purpose in such an excellent way.
The small (and free) Wagner:Werk museum inside the building tells the story of the Postsparkasse, the architectural competition, and the groundbreaking nature of the winning design.

The impact of that design is best exemplified by standing at the entrance and looking back across Stubenring to the government buildings opposite.
This new location for the imperial Ministry of War went up at about the same time as the Postsparkasse (Wagner even bid – unsuccessfully – on the project).
The ministry’s design still clung largely to old-style architectural approaches that followed the principles of historicism. The contrast is quite remarkable.
The Savings Bank continued as bank offices with service counters for most of its history. At the time of writing, it was slowly morphing into a home for academic institutions, such as the University of Applied Arts Vienna.
As a result, you can go inside. Carry on straight up to enter the Grosse Kassenhalle or main counter space, which looks like it teleported straight out of 1906. The Viennese of the time must have felt like they had stepped into the future.
The Kassenhalle has a small self-service café within. The chairs slip neatly into the bentwood tradition, while mirrored tabletops create the kind of images that attract a multitude of likes on Instagram.
With everything seemingly as it once was, your imagination begins to fill with bewhiskered gentlemen and long-skirted ladies. Close your eyes to hear the staccato of ink stamps on paper and the constant scratching of fountain pens across a thousand slips of paper.
How to get to the Postsparkasse building
Although in the old town, the building sits off to one side of the traditional tourist areas.
(Incidentally, the monument you see as you face the front entrance from Stubenring (next to the underground car park) is in honour of Georg Coch, the Postsparkasse’s founder and first director.)
Subway: a short walk from Schwedenplatz (U1 and U4) and Stubentor (U3).
Tram/bus: the tram lines 1 and 2 both stop at Schwedenplatz and the nearby Julius-Raab-Platz stop. The 2 also goes to Stubentor.
You’re not far from some other lovely examples of Modernist or Jugendstil buildings. Fleischmarkt is but a block away and offers the Residenzpalast, the Meinlhaus, and other turn-of-the-century architectural joys: see here for details.
Address: Georg-Coch-Platz 2, 1010 Vienna
