About

Benzenberg-Sternwarte is a historic observatory in Düsseldorf, founded in 1843 by physicist Johann Friedrich Benzenberg. Originally named “Charlottenruhe” in memory of Benzenberg’s late wife, the observatory was located in Bilk and equipped with a powerful refracting telescope for celestial measurements. After Benzenberg’s death in 1846, the site was bequeathed to the city, becoming a center for astronomical research. Between 1852 and 1890, astronomer C. Robert Luther discovered 24 asteroids here, known as the “Düsseldorf planets.” Though the original building was destroyed during WWII bombings in 1943, its legacy lives on through a commemorative benchmark and the modern Benzenberg-Sternwarte at Schloss-Gymnasium Benrath, which continues to inspire students and visitors with public stargazing events and educational programs.

Location

The Benzenberg-Sternwarte is historically located in the Bilk district of Düsseldorf. It was originally founded in 1843 by Johann Friedrich Benzenberg as a private observatory, famously known for its large refracting telescope. After multiple relocations and rebuilds, the current observatory is being established on the rooftop of the new Schloß-Gymnasium at Benrodestraße, near the city center. This location offers a clearer sky view and is close to educational institutions in Düsseldorf. Nearby are the Hofgarten park and the central districts of Bilk and Friedrichstadt, making it accessible from the vibrant cultural and academic heart of the city. The site continues the tradition of astronomy in Düsseldorf while integrating modern facilities for education and observation.
