Welcome to the wildly unique and fascinating Vienna Clock Museum (Uhrenmuseum Wien), where you can experience three thousand timepieces ticking away for your pleasure and amusement. There are many exhibits worth checking out, the oldest going all the way back to the 15th century. This impressive inventory can largely be traced back to two private collections. The first is from middle-school teacher and first leader of the house, Rudolf Kafan. The other collection is from the writer Marie von Ebner-Eschenbach.
Some highlights include the astronomical art clock by David a Sancto Cajetano. This phenomenon shows the time, the length of the day, and the orbital period of planets. Other exhibits are the Laterndluhr style regulations, great examples of the art of Viennese clockmaking. Check out the "Zappler", the smallest clock in the collection, which can fit under a thimble. The heaviest one is the tower clock of St. Stephen’s Cathedral, made from solid cast iron.
