The Hornberg is a hill ridge, about 2.5 kilometres long, with three kuppen that reaches a maximum height of 580 m above sea level (NHN)[1] making it the highest point of the Virngrund region in the German state of Baden-Württemberg.

The ridge is a continuation of the small plateau around Ellenberg in the Württemberg county of Ostalbkreis, with which it is only linked by a narrow strip of land as a result of valleys to the west and east.

Compared with the plateau it is only slightly, or even insignificantly prominent, the aforementioned valleys and, especially the northern foreland around Georgenstadt, however, lie some 60–80 metres lower down.

Description of the kuppen with their heights above Normalhöhennull (NHN) and geocoordinates:[1] (579 m, 49°1′11.2″N 10°12′44″E / 49.019778°N 10.21222°E / 49.019778; 10.21222)To the north is the hillside forest, to the south is open pasture.

In addition to a transmission site here, there is also a small football pitch (Bolzplatz) and 3 tennis courts.. Just under 450 m south-southeast on the other side of the landbridge to the Ellenberg Plateau stands the Ellenberg water tower (150 m³ capacity, 29 m high), which has an observation platform.
