A collection of 3000 clocks of all types, including a prized 18th-century astronomical clock.
Jewish Museum Judenplatz
A second branch of the Jewish Museum on Dorotheergasse. Underneath the Judenplatz (the Jewish Square) is an underground medieval synagogue excavation. Amazingly, the synagogue was destroyed centuries ago, but its existence was remembered by the area's inhabitants up to the 20th century.
This venue hosts special exhibits of internationally-renowned artists; past exhibits have displayed work by Egon Schiele, Oskar Kokoschka, Cézanne, Picasso, and Van Gogh.
This gothic church was used by sailors on the Danube river. Its name refers to the former location near the river. Communion celebrations are held in German, French, and Czech.

Museum at the Scottish Monastery
