After the open-cast mine was closed in 1991, the idea of bringing together the large machines that remained on the site and using them as a museum on a remaining pillar that protrudes into the open-cast mine, today's peninsula, was born, based on a diploma thesis submitted to the Bauhaus Dessau Foundation in 1992 by the architect Martin Brück. In addition to the Bauhaus Foundation, the Expo 2000 Society Saxony Anhalt GmbH and the Lausitzer and Central German Mining Management Company were involved in the design of the site, which was designated as a regional project for Expo 2000. The official founding of the "city of iron" was completed with the unveiling of the town sign by the then Minister of Economic Affairs of Saxony-Anhalt, Klaus Schucht, on December 14, 1995. Ferropolis was opened to the public in July 2000. The opening gala concert was conducted by the Greek composer Mikis Theodorakis; the accompanying light show was staged by Gert Hof. Bauhaus and Expo-Gesellschaft withdrew from the operating company Ferropolis GmbH at the end of 2001; the main shareholder is currently (2019) the city of Gräfenhainichen.
