The Einstein Tower is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany designed by architect Erich Mendelsohn. It was built for astronomer Erwin Finlay Freundlich to support experiments and observations to validate Albert Einstein's relativity theory. The building was first conceived around 1917, built from 1920 to 1921 after a fund-raising drive, and became operational in 1924. It is still a working solar observatory today as part of the Astrophysical Institute of Potsdam.
