Alheimer, Mountain summit in Hesse, Germany.

Alheimer is a mountain summit in the Stölzinger Hills with steep slopes covered in dense forest throughout. A 22-meter observation tower stands at the peak and serves as a focal point for visitors.

The Alheimerturm was built from stone between 1929 and 1930 and is 21 metres high. It stands within a war memorial with several stones commemorating soldiers and civilian victims of both World Wars from the villages of the former Rotenburg district. The whole site, tower included, is a protected monument.

The name Alheimer may come from "Allmende", the common land shared by surrounding villages; a local legend instead tells of villagers who climbed to raid a robbers' nest at the hilltop hunting lodge and found it empty, one shouting "Ach, die sind ja all heim!". The hill gave its name to the municipality of Alheim, created in 1972. The summit area holds a war memorial with stones for soldiers and civilian victims of the old Rotenburg district.

Two narrow access roads with Alheimer signs end at car parks near Hof Guttels and at Seifertshausen; from there the summit is reached on foot, the last stretch being a somewhat strenuous climb. The 21 m stone tower's platform lies 20 m up, reached by over 111 steps.

The tower stands within a war memorial with several stones commemorating soldiers and civilian victims from the villages of the old Rotenburg district in both World Wars. The whole complex, tower included, is a protected monument.
