Observatory of Strasbourg Observatory of Strasbourg The Observatory of Strasbourg is an astronomical observatory in Strasbourg, France. Following the Franco-Prussian War of 1870–71, the city of Strasbourg became part of the German Empire. The University of Strasbourg was refounded in 1872 and a new observatory began construction in 1875 in the Neustadt district. The main instrument was a 50 cm Repsold refractor, which saw first light in 1880 (see Great refractor). At the time this was the largest instrument in the German Empire. In 1881, the ninth General Assembly of the Astronomische Gesellschaft met in Strasbourg to mark the official inauguration.The observatory site
