Potsdam, Einstein Tower

The Einstein Tower is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany.

It was built by Erich Mendelsohn on the summit of the Potsdam Telegraphenberg to house a solar telescope designed by the astronomer Erwin Finlay-Freundlich. The telescope supports experiments and observations to validate (or disprove) Albert Einstein's relativity theory. The building was first conceived around 1917, built from 1919 to 1921 after a fund-raising drive, and became operational in 1924. The building was heavily damaged by Allied bombing during World War II, it underwent a full renovation in 1999.

The Einstein Tower can be found on a commemorative medal that was issued in East Germany in 1990.
