Location

Observatoire Astronomique de Strasbourg is located on Boulevard de l'Observatoire within the Observatoire-Botanique neighborhood in the Neustadt UNESCO World Heritage district, north of Place de la République and adjacent to the botanical gardens. Constructed from 1877-1881 under German imperial direction by architect Hermann Eggert, this neo-Renaissance complex comprises the iconic Grande Coupole housing a 49cm Repsold equatorial refractor telescope—one of France's largest—the L-shaped meridian pavilion with north-south domes for precise stellar observations, and the director's residence linked by corridors, all designed for vibration-free stability amid marshy terrain. Modernized post-1918 with electricity and a planetarium in the former Cauchoix meridian room, it preserves over 200 historic instruments in its "crypt of stars" museum while serving ongoing research and teaching. Nearby lie Parc des Contades and Jardin de la Place de la République to the south, Église Saint-Thomas, Palais du Rhin, National Library, and tram lines B/E at République stop, with 15-minute walks to Cathédrale Notre-Dame and Grande Île.
