Schöpfl is the highest hill (893 m; 2,930 ft) in the Vienna Woods mountain range, the north-easternmost part of the Alps.

The main top of the wooded mountain range carries a high observation tower which enables a 100 km (60 mi) sight to the Northern Limestone Alps in the west and the Carpathian Mountains in the east.

882 m (2,894 ft) above sea level) is the University of Vienna's Leopold Figl observatory.

Its largest instrument is a telescope with a primary mirror of 1.5 m (5 ft), which was constructed in the 1960s.

A second tower was built recently for some smaller astrophysical telescopes.
