Schöpfl
Schöpfl is the highest hill (893 m) in the Wienerwald mountain range (Vienna woods), the north-easternmost part of the Alps. Geologically, it belongs to the flysch Alps.
The main top of the wooded mountain range carries a high observation tower which enables a 100 km sight to the Northern Limestone Alps in the west and the Carpathian Mountains in the east.
At the Mitterschöpfl (approx. 880 m above sea level), the University of Vienna's Leopold Figl observatory is located. Its largest instrument is a telescope with a primary mirror of 1.6 m which was constructed in the 1960s. A second tower was built recently for some smaller astrophysical telescopes.
