Sankt Andreasberg Observatory
In 2014, a very special observatory was opened in Sankt Andreasberg in the Upper Harz Mountains: the Sternwarte Sankt Andreasberg. The project is supported and financed by the non-profit association Sternwarte Sankt Andreasberg e.V. The aim is to make the sky accessible to all people - young and old, disabled and non-disabled - and to impart astronomical knowledge.
The grounds of the observatory at the Internationales Haus Sonnenberg offer excellent viewing conditions and low turbidity air at an altitude of 710 m above sea level.
The observatory's special features are for everyone: Experience nature, culture and science without barriers.
