Sternwarte

Hidden among the rolling hills of the Eifel region, about 60 km southwest of Bonn, lies the Sternwarte. The Sternwarte began its life not here, but amidst the growing city of Bonn. In the mid-19th century, a friendship between the astronomer Friedrich Wilhelm August Argelander and the Prussian King Friedrich Wilhelm IV led to the construction of an observatory in Bonn. Designed by the renowned architect Karl Friedrich Schinkel, the Bonn Observatory was completed in 1844. It became a hub for astronomical discoveries, including Argelander’s famous Bonner Durchmusterung, a comprehensive star catalog. However, as Bonn grew, the city lights began to obscure the night sky. The observatory could no longer function effectively. In the late 1940s, the search for a new location began. The Sternwarte found its new home atop the Hoher List mountain. This area offered the dark skies essential for astronomical observation. The relocation process began. By 1954, the Sternwarte, now known as the Hoher List Observatory, was inaugurated at its new site. It housed a 50-cm Schmidt telescope in its first dome. The observatory continued to expand. The historic double refractor telescope from the original Bonn Observatory was installed in a new dome in 1964. The largest and most modern telescope at the time, a 1-m Cassegrain telescope, was added in 1966. Over the decades, the Sternwarte served as a training ground for many astronomy students. They contributed to important scientific projects related to the position, motion, brightness, and color of stars in our Milky Way. Despite its rich history, the observatory was eventually closed down by the University of Bonn in 2012. However, thanks to the efforts of a dedicated group of astronomy enthusiasts, the Astronomische Vereinigung Vulkaneifel am Hoher List (AVV), the Sternwarte lives on. Today, it is a place where the public can experience the wonders of the universe. They offer guided tours and public observing events, ensuring that the legacy of the Sternwarte continues to shine brightly.
