In addition, from 1950 to 1960 there was an observatory on the eastern summit of the Wendelstein, consisting of an observation dome and a residential house. There, the astronomer Rudolf Kühn carried out research. The facility was completely demolished in 1965, only the remains of the foundations are still visible. Where the observation dome once stood, a wind turbine was later built, but that, too, was dismantled in 2007.
