In 1487 Berlin acquired Woltersdorf. Then in 1550 a lock was built between the Flakensee and the Kalksee, the same year the first church of Woltersdorf was built. Between 1618 till 1648 Woltesdorf was desolated (Thirty Years' War) and temporarily uninhabited. About 1886 a touristic observation tower is built on top of the Kranichsberge. It granted a great perspective from a height of 105 meters, and on clear days you were able to see the Berliner Fernsehturm. Inside the tower today is an exhibition "When Woltersdorf still was Hollywood" (German ""Als Woltersdorf noch Hollywood war""). It recalls the 1920s, where Joe May shot famous movies ("Das indische Grabmal" (1920), "Herrin der Welt" (1919) and "Der Tiger von Eschnapur"). Today you are able to find remains of the movie scenery on site.
