Hubertushöhe, Protected hill in Graz, Austria

Hubertushöhe is a 562-metre hill of the Plabutsch ridge in Graz, Styria, between the districts of Gösting and Eggenberg, with Algersdorf at its foot. On its summit stands the Kernstockwarte, a low circular viewing platform built of rubble stone with a winding external staircase and iron railing. The northeast slope has been quarried, and the summit is overgrown with bush forest.

The Kernstockwarte on the Hubertushöhe was requested on 25 September 1928 by Josef Valentinitsch, chairman of the Eggenberger Verschönerungsverein, and built in 1928/29 with donations from Eggenberg citizens; the builder was city master builder Franz Spath. The round structure of quarry stone, hollow inside, is a protected monument. During the Second World War its hollow space served as a listening post.

The hill takes its name from the Gasthaus Hubertushöhe, the inn at the top of the road climbing from Algersdorf; the street name Weingartenweg recalls the vineyards once worked east of Graz, and some vines still grow on the slopes. The Kernstockwarte is named after the poet Ottokar Kernstock, author of the Hakenkreuzlied, and is to be renamed Warte zur Hubertushöhe.

The Kernstockwarte platform is reached by a winding outdoor stair with an iron railing; the hollow round building is entered by ladder. The Kernstockweg, a 16 km trail from Gösting to Straßgang, runs along the Plabutsch ridge but not directly past the tower. Bushes limit the view from the top.

The Kernstockwarte's hollow round structure, built of rough stone in 1928/29 with donations from Eggenberg citizens, served as a listening post during World War II; a ladder inside leads to the space. The tower is named after poet Ottokar Kernstock, and a renaming to Warte zur Hubertushöhe is proposed because of his Nazi-linked Hakenkreuzlied.
