The Hohenberg is a 552 m above sea level (NN) high hill in the Palatinate Forest, in the municipalities of Birkweiler, Queichhambach and Siebeldingen.

[1] At its summit is an observation tower, a refuge hut and starting ramps for hang gliders.

From August to September 1879 an observation tower, just under 9 metres high, was erected at the summit by the conservation societies of Annweiler and Landau.

In the 1960s the first stones worked loose as a result of age and in 1970 the eastern side of the tower collapsed.

In 1971, DM 30,000 was invested in the building of an access track for motor vehicles and the rebuilding of the tower.
