It is the famous watch house in Vienna, and it has every kind of watch imaginable. It is a unique place, as there are not many other places like it in all of Europe. The site is inside an old Viennese house, some of which are still intact from the Middle Ages, and timekeeping devices from the 15th century are on display here. The museum goes beyond diversity, really trying to share the history of the evolution of clocks over time.
