With 542 m above sea level, it is the highest point of Vienna. The Habsburgerwarte, a 27-m-tall tower from 1888, on top of the Hermanskogel is open on weekends in the summer. It used to be km 0 for cartographic measurements in the Austria-Hungarian empire.
The Hermannskogel is a hill in Döbling, the 19th district of Vienna. At 542 metres above sea level, it is the highest natural point of Vienna. It lies on the border to Lower Austria.

The hill has a beautiful view over the Viennese vineyards and down the Danube. On clear days one clearly sees the Viennese historic center including the cathedral. Many bike or hike trails into the Wienerwald start from here.
The climbing hall is part of the sport center Marswiese. It offers various climbing courses.
Grinzinger Pfarrkirche
Built in the 15th century, the church was burned in 1529 and 1683, during the first and second Turkish sieges of Vienna, and severely damaged during World War II. However one treasure did survive: the organ, on which both Beethoven and Schubert used to perform. The organ was modified several times since then and had fallen into severe disrepair, but in 1997 it was completely restored by a master organ builder and is now again played regularly.
Kirche am Leopoldsberg / Leopoldikapelln
Dedicated to the patron saint of Vienna, this small church was established in 1679, and its current appearance dates to the first part of the 18th century. The building is on top of 425-m-high Leopoldsberg, with lovely views of Vienna and the surrounding area. Following restoration work of the nearby medieval fortress, the church re-opened to the public in 2018.
A lovely park, inaugurated in 1888 by Austrian emperor Franz Joseph. The park is at the site of and named after a Turkish entrenchment ("Türken-Schanze") of the first Turkish siege on Vienna in 1529. It is close to the University of Agriculture, and features a variety of botanic rarities from all continents.
