The Albert Einstein Science Park is located on the hill Telegrafenberg in Potsdam, Germany. The park was named after the physicist Albert Einstein. The best known buildings in the park are the Einstein Tower, an astrophysical observatory that was built to perform checks of Einstein's theory of General Relativity; and the Great Refractor of Potsdam, which today belong to the Astrophysical Institute Potsdam. These buildings, along with various astronomical, meteorological, and geophysical observatories were integrated into an English country garden.
