Hagberg, Mountain summit in Welzheim Forest, Germany

Hagberg is a mountain summit in Baden-Württemberg's Welzheim Forest that rises to 585 meters and offers views across forested valleys and ridges. The landscape surrounding the peak is shaped by dense woodlands interrupted by open meadows.

The Hagberg is said to have formed part of the border between Swabians and Franks in earlier times, as did the Asperg and the Hesselberg. A first wooden observation tower was erected on the summit in 1901; it was replaced by a tower in its present form before the First World War. In 1936 the Schwäbischer Albverein acquired the tower, and during the Second World War the Luftwaffe set up an observation post in it, removing the upper pagoda.

The Hagbergturm has been maintained by the Schwäbischer Albverein since 1936, and from Easter to the end of October it is staffed on Sundays and holidays. On other days the Gschwend branch of the Jura Club can open it on request. The tower is also the starting point for walks around Gschwend.

A narrow road branches off the L 1080 before Gschwend and passes Haghof, Sturmhof and Wasserhof; a small car park lies at the western edge of Sturmhof, about 500 metres from the summit. The Main-Neckar-Rhein-Weg runs across the upper slopes southwest of the peak. The tower is open Sundays and holidays from Easter to the end of October.

The 23-metre Hagberg Tower on the summit is built of wood on a reinforced concrete pedestal and topped by two pagoda-like structures. During the Second World War the Luftwaffe set up an observation post in it and the upper pagoda was removed; the tower was rebuilt in its original shape and reopened on 21 June 1980.
