Estação de Triangulação do Wendelstein

At Grünbach on the Felsenrunde

The Wendelstein near Grünbach is a worthwhile hiking destination.

The Wendelstein has been protected as a geological natural monument since November 5, 1938. A triangulation column dated 1864 was erected on the highest part of the rock, representing a second-order survey point in the course of the historic Saxon national survey.
The Royal Saxon Triangulation (here with its historical proper name) is a national survey carried out between 1862 and 1890 on the territory of the Kingdom of Saxony, with the simultaneous creation of a trigonometric network.
The goal was to record the national territory with scientific and geodetic precision and, by establishing permanently marked reference points, to create the basis for the production of accurate maps. The Großenhain baseline was chosen as the scale base.
