Rosenkogel, Mountain summit in the Lavanttal Alps, Austria

Rosenkogel, also called Spitzkogel, is a 1362 m summit at the eastern end of a Koralpe spur in the Lavanttal Alps. Its top consists partly of eclogite, rock over half a billion years old, which gives the peak a relatively pointed shape. A small chapel and a summit cross stand by the top.

Until the 19th century the ridge of the Rosenkogel marked the border between the Marburg and Graz districts. A 1225 document mentions the Greimstrasse from Gams over the Greim area toward the Hebalm. West of the summit, the name Absetzwirt recalls a reloading point where carriers had to hand over loads at the boundary of a lordship.

The name Rosenkogel comes from the alpine roses growing on its slopes, while Spitzkogel refers to the pointed summit of eclogite, a rock over half a billion years old. The former municipality of Marhof bore two silver roses in its coat of arms. Near the summit stands the Amreich-Kapelle, rebuilt from 2016; its 65 kg bell, cast by the firm Grassmayer, was consecrated on 19 June 2022 and bears the inscription "Hl. Franziskus schütze Wald, Mensch und Tier".

Access is via the LH 645 Sallegger Straße from Bad Gams or Stainz; a side road climbs to the Absetzwirt inn on a saddle about 800 m west of the summit, where the hiking trail begins. The eastern approach roads are steep and winding. The summit lies in a protected landscape area and holds a small chapel and a summit cross.

The summit lies partly on eclogite, a rock over half a billion years old and among the hardest and densest found at the Earth's surface. The French mineralogist René-Just Haüy first identified and named it in the 18th century during a scientific journey through southern western Styria. The boundary between this rock and the surrounding stone shows as a clear break in slope.
