Darmstadt is located 20 kilometers south of Frankfurt, on the edge of a valley abutting the Langenberg hills to the south. It was the capital of the state of Hesse until right after World War II, when the capital moved to Wiesbaden because of major war damage to the inner city.
Darmstadt is the center of German high technology education, with several universities. It is a major center for the European Space Agency and for chemical research; several of the heaviest chemical elements were discovered here and element 110, Darmstadtium, is named after the city. Many new economy companies are also located here, including the headquarters of Europe's largest internet service provider.
