The many cliff-like layers on the south-western approach to the Hermannskogel clearly show the hill's geological make-up.

The Kahlenberg and Leopoldsberg, behind which lie the Wiener Pforte, where the Danube breaks through the Wienerwald, are three kilometres to the east of the Hermannskogel.

On the side of the hill, in a depression between Sievering and Weidling, is the probable former site of the village Kogelbrunn, which lived from viticulture and which is mentioned for the first time in a document from 1237 as chogelbrunne.

The relief army summoned from the Kingdom of Saxony and other parts of the empire that lifted the second siege of Vienna camped here in 1683.

The Habsburgwarte that stands atop the Hermannskogel was established as the kilometre zero of cartographic measurements in Austria-Hungary at the start of the 19th century.
