The Kahlenberg is 484 metres high and has a long history. It was given as a gift by Emperor Ferdinand II. to the Camaldolese Order in 1628. At the heart of the monastery built there arose St. Josephs' Church. However, the Kahlenberg was actually made famous by Polish King Sobiesky, who marched over the Kahlenberg with his army in 1683 and liberated Vienna at the very last minute from the Turkish occupiers.
Today, the Kahlenberg is above all a popular excursion destination and the top can be reached in about four hours on Vienna's City Hiking Trail 1. At the highest point of the mountain is the Stefaniewarte. This 22 metre-tall viewing tower was built in 1887 and named after Crown Princess Stefanie of Belgium. Just below the summit stands the Baroque St. Joseph's Church, whose black Madonna made it a popular pilgrimage church. From there, you arrive at the panorama terrace, which invites you to stay awhile and gaze down on Vienna. A restaurant and takeaway cafe offer not only beautiful views, but also Viennese delights.
The City Hiking Trail 1a leads to the neighbouring 425 metre-high Leopoldsberg. A special feature here is the 1.5 kilometre-long Nasenweg with its unique fauna and flora and its impressive view of the Danube.
Those who would prefer not to walk can reach the Kahlenberg in comfort by bus (line 38A via Grinzing), by car (via Grinzing and the Höhenstrasse) or by Heurigen Express from Nussdorf (April to October).
