The Altenberg is the highest summit in the Limpurg Hills in southwest Germany, reaching a height of 564.7 m above sea level (NHN) and rising some 60 metres above the surrounding area.

It lies east of Hohenberg, a village in the municipality of Sulzbach-Laufen, within the county of Schwäbisch Hall in the state of Baden-Württemberg.

At the summit is the Altenberg Tower, a 38.3-metre-high[1] observation tower.

The tower was opened on 7 October 2007[2] and measures 36 metres from the ground to the observation platform.

As a result, the fully covered viewing point is at a height of about 600 m.
