Located on the well-known Karlsplatz, the heritage-protected Wien Museum is a building from the 1950s. It hosts a permanent exhibition on Vienna — a collection of both historical as well as fine art items starting from the Neolithic times up until the interwar period. The current temporary exhibition opened its doors in March. It’s about the life and work of the architect Otto Wagner, who immensely influenced Viennese architecture and is said to be one of the initiators of early modernism, especially on matters of functionality, materials and construction. The exhibition itself is extensive, with hundreds of drawings, photographs, architectural models and furniture. If the visit sparked your interest, I would suggest to subsequently visit an actual Otto Wagner building, like the Majolika house or the Kirche am Steinhof.
When going to the Wien Museum, also take note of the ambience of the building itself. It starts with the elegant golden door frames and handles, the old school toilets (“D” stands for Damen and “H” for Herren, which is the German expression for women & men), the symmetric windows (again with golden frames) in the covered court yard, and the overall radiant ’50s vibe. I love visiting the Wien Museum, because it takes me back to a city from former generations and makes me feel connected and all mingled up with Vienna, my city.
If you have the possibility, visit on the first Sunday of the month, as the entry is free of charge on that day.
