Stellberg, Mountain summit in Schönbuch Nature Reserve, Germany.

Stellberg is a mountain summit in the Schönbuch Nature Reserve, reaching about 580 meters in elevation. The peak sits within a forested landscape dotted with hiking trails that connect to other nearby summits and mountain huts in the region.

A sandstone quarry once stood on the Stellberg; from about the 1950s it was used as a landfill, and from the mid-1970s the pit was backfilled with earth. Reclamation began in the 1990s and ended with stones placed on the plateau as seats, arranged to recall a Stone Age cult site. Landscape measures kept the summit usable as a viewpoint.

The plateau of the former quarry is lined with stones placed as seats and arranged to recall a Stone Age cult site, a deliberate design choice made when recultivation ended in the 1990s. Seven information panels along the access path explain the Schönbuchturm's features, and one board lists figures and facts about the tower.

The L 1184 from Herrenberg to Hildrizhausen runs just south of the former quarry. About 500 m west stands the Naturfreundehaus Herrenberg, and hiker parking is available near the Waldfriedhof south of the road. A short access path leads from there to the Schönbuchturm in a few minutes, lined with seven information panels.

The summit is an artificial plateau: a former sandstone quarry was used as a landfill from the 1950s, filled with earth from the mid-1970s and recultivated from the 1990s. Stones placed on the plateau as seats are arranged to recall a Stone Age cult site.
