Station 4 Potsdam Telegraphenberg

Station 4 on Telegraphenberg in Potsdam formed part of an optical telegraph line between Berlin and Koblenz. The optical line operated between 1832 and 1852. Visual signals carried messages between elevated stations, creating an early long-distance communication system in the Kingdom of Prussia. The hill was once known by the name Brauhausberg. Written records first used the name Telegraphenberg in 1839, linking the place to its communications history. The station occupied a former military fortification on the hill. Its elevated position supported clear sightlines to neighbouring stations along the route. The original station no longer stands today. A replica signal mast marks the site’s historical connection. The area forms part of the Albert Einstein Science Park. The park brings scientific institutions into a landscape where military history and communication technology meet. The public grounds include this historic telecommunications site. Station 4 connects Potsdam’s Telegraphenberg with a period when visible signals moved information across Prussia. The hill preserves a record of early long-distance communication.
