Wurmberg, Mountain summit in Lower Saxony, Germany

Wurmberg is a 971.2 m mountain in the Harz, the highest in Lower Saxony, rising about 3.3 km north of Braunlage. Its summit holds a rectangular concrete building with rows of square windows and a "Wurmberg" sign, topped by a steel framework carrying a gondola-like platform on angled struts. A lower block signed "Gondel" extends to the right.

The name Wormberch appears in 13th-century documents of the County of Regenstein-Blankenburg, tied to iron ore mining. Around 1850 a trig post was erected on the summit, replaced in 1890 by a wooden tower that stood until 1930. In 1922 a wooden ski jump with a 28-metre starting tower was built, and since 1963/65 the gondola lift has run from Braunlage; it was fully renovated in 1997.

The name Wormberch appears in 13th-century records of the County of Regenstein-Blankenburg, tied to iron ore mining; no convincing derivation of the name has been found. Heinrich Pröhle collected Harz legends in 1851 from Braunlage residents, who told him a pagan temple once stood on the summit. The stone staircase is called Heidentreppe, and since the 20th century Hexentreppe.

Visitors can reach the summit via marked hiking trails or by cable car, which runs during the main season from spring to fall. The routes vary in difficulty, so there are options for different fitness levels.

On the summit plateau, a container holds one of the 25 measuring sites of Lower Saxony's air quality monitoring network. Since September 2007 an amateur radio relay with the callsign DB0WUR has also transmitted from the mountain on 438.550 MHz, reaching parts of Lower Saxony, Thuringia, Hesse and Saxony-Anhalt.
