Langenberg, Mountain summit in Bad Harzburg, Germany.

Langenberg is a mountain summit near Bad Harzburg that rises to 304 meters and is covered with forest. The peak sits within the Harz mountain range and connects to surrounding trails that link to other peaks in the region.

The name Langenberg appears in documents as "silva Langenberg" between 1285 and 1296 and as "der Langenberch" in 1309, both tied to the Goslar Cathedral chapter. Chalk was quarried at the hill's western tip from at least the mid-18th century, and in 1871 Adolph Willikens opened the large Kalkröse quarry there. The Hansa Pit, founded in 1861 after Wilhelm Castendyck found oolitic iron ore, operated until 23 August 1960.

The name simply means "long mountain" in German, referring to the ridge's elongated, hercynian profile parallel to the Harz. The hill was first recorded between 1285 and 1296 as "silva Langenberg" and in 1309 as "der Langenberch", belonging to the Goslar Cathedral chapter. Today the disused quarry, where Holger Lüdtke found a sauropod tooth in 1998, is fenced off and privately owned.

Multiple marked trails from Bad Harzburg lead to the summit and suit different skill levels. Parking areas sit at the base of main routes, and information boards show the available climbing options.

From the summit you can see dense forest-covered Harz mountains on one side and open lowland areas on the other. This contrast clearly shows where the mountain range ends and the plains begin.
