Einstein Tower
Germany
The 186th tallest tower in the world
The Einstein Tower (Einsteinturm) is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany. The Tower was built by architect Erich Mendelsohn in 1924. It was built 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. Although Einstein never worked there, he supported the construction and operation of the telescope. Einstein Tower is a working solar observatory today as part of the Leibniz Institute for Astrophysics Potsdam.
