Franz Kaiser Sternwarte

About

Franz Kaiser Sternwarte in Wiesbaden is a public observatory operated by the Astronomische Gesellschaft Urania e. V., one of Germany’s oldest astronomical societies, founded in 1925 by Dr. Franz Kaiser. A native of Wiesbaden and renowned astronomer, Kaiser discovered 21 minor planets, two of which he named after his hometown. The observatory, originally housed in the Oranienschule, was destroyed during World War II but restored in 1954 and later relocated to the roof of the Martin-Niemöller-Schule. Today, it features a 30 cm Maksutov reflector telescope and offers regular observation evenings, solar viewings, lectures, and special events like Astronomical Week. The society promotes public engagement with astronomy, collaborating with local schools and cultural institutions. The Sternwarte blends scientific heritage with community outreach, making the cosmos accessible to all. It stands as a tribute to Kaiser’s legacy and Wiesbaden’s enduring fascination with the stars.
