Longwave transmitter Europe 1, Radio transmitter in Überherrn, Germany
The Longwave transmitter Europe 1 is a broadcasting facility in Überherrn near the French border, distinguished by its remarkable concrete shell roof built without internal supporting pillars. The installation sits prominently on Sauberg hill and once served as Germany's most powerful radio station.
The facility began broadcasting in 1955 as a post-war technological project and gradually became an engineering achievement. A power increase to 2000 kW in 1976 established it as Germany's strongest broadcasting presence.
The transmission hall represents a milestone in architectural engineering, earning recognition as a Historical Landmark of German Engineering in September 2021.
Visits to the transmission hall require advance registration by contacting the municipality via email or phone. Guided tours with expert explanations about the building's engineering are offered regularly throughout the year.
The concrete shell roof was the first of its kind worldwide for a building of this scale and set standards for innovative construction. This design allowed for an interior free of support columns, which was revolutionary for its time.
