Renovations complete on Einstein Tower, observatory built to represent Einstein's theory of relativity

A solar observatory built to substantiate Albert Einstein’s theory of relativity has been reopened near the German capital after a renovation project to preserve it for future generations. [...] “The Einstein Tower might no longer be at the forefront of research, but it’s not a mere museum piece [...] Following its renovation it’s probably now in a better condition than it was when it was inaugurated almost 100 years ago”

Located on Telegraph Hill in Potsdam, 16 miles southwest of Berlin, Einsteinturm (Einstein Tower) underwent a year of renovations to address its many cracks and extensive dampness, and to preserve its domed zinc roof. The restoration cost approximately $1.2 million.

The structure was built between 1920 and 1922 by German-British architect Erich Mendelsohn in collaboration with astronomer Erwin Finlay-Freundlich. The approximately 66-foot tower was designed to represent and verify Einstein’s theory of relativity. It is considered a landmark in expressionist architecture, with its lack of right angles, organic form, and curved wooden staircase. Originally planned in concrete, a lack of materials after the First World War meant it was built using stucco-covered brick.

The tower is still in operation today as a working solar observatory, run by the Leibniz Institute for Astrophysics (AIP). In addition, the working telescopes are the original ones installed nearly a century ago.
