Vienna’s Uhrenmuseum (Clock Museum) can be found in the heart of the city, inside a unique and historically relevant building. Nowadays an annex of the Wien Museum Group, the Clock Museum dates back to 1917 when it was established by merging two important private collections into one permanent exhibition of time pieces. Those two collections belonged to Rudolf Kaftan, a secondary teacher who then became the first director of the museum, and to Austrian writer Marie von Ebner-Eschenbach. Showcasing as many as 700 clocks from all over the world, the Clock Museum is ranked among the most significant clock collections of Europe.

Upon entering, visitors are taken on a journey through time, highlighting scientific achievements, social dynamics and technological perfection on all three floors of the building. Different eras such as Biedermeier or the Belle Epoque are represented by all kinds of astronomical and artful clocks. The highlight is the Cajetano Clock, a masterpiece of 18th-century-monk David Sancto Cajetano, showing the time in different places as well as the movement of the planets.
