The Burgstein is a rock formation, about 10 metres (33 ft) high, in the valley of the Ilm in Langewiesen in the central German state of Thuringia. It is made from quartz porphyry and has been a geological natural monument since 1939. It was formed when the Ilm carved out its valley and washed away the surrounding rock. When the Ilmenau–Großbreitenbach railway was built in 1881 it was exposed again because rock at its foot was removed in order to lay the railway track. The rock dates to the Pennsylvanian sub-period and belongs to the Möhrenbach Formation. The origin of its name is not clear (Burgstein literally means "castle rock"). In Langewiesen, the road of Burgstein is named after the rock.

Ilm-Kreis is a district in Thuringia, Germany. It is bounded by (from the north and clockwise) the city of Erfurt, the districts of Weimarer Land, Saalfeld-Rudolstadt and Hildburghausen, the city of Suhl, and the districts of Schmalkalden-Meiningen and Gotha. It is named after the river Ilm, flowing through the district.

The Ehrenberg is a hill to the east of Ilmenau, rising to a height of 528 metres and standing opposite the Tragberg. The border between Ilmenau and Langewiesen runs over its summit, which is marked by a large wooden cross. It is home to part of the campus of the Technische Universität Ilmenau (Technical University of Ilmenau) and the Bundesanstalt für Wasserbau (Federal Institute for Hydraulic Engineering). On 22 July 2006, around 6,000 square metres of the Ehrenberg were destroyed in a forest fire, although damage to buildings was limited. The body of the Ehrenberg itself is notable geologically for containing hydrobiotite, sometimes also called voigtite.
