Archenhold Observatory
About

Located in Berlin’s Treptower Park, the Archenhold Observatory is Germany’s oldest and largest public observatory, founded in 1896. Its most iconic feature is the Great Refractor, a 21-meter-long movable telescope nicknamed the “Celestial Cannon”—still the longest of its kind in the world. Originally built for the Great Industrial Exposition, the observatory became a permanent fixture thanks to Friedrich Simon Archenhold’s vision of public science education. The site includes the historic Einstein Hall, where Albert Einstein gave his first public lecture on General Relativity in 1915, as well as a museum, planetarium, and solar physics exhibition. Visitors of all ages can explore astronomy through guided tours, lectures, and interactive programs.
