A museum in the lake – The pile dwellings of Unteruhldingen

District administrator Hermann Levinger had the idea: in his mind’s eye he saw an open-air museum with reconstructions that were true to the original and based on the latest research. The execution and expertise lay with the mayor of Unteruhldingen, pile dwelling researcher Georg Sulger. Victor Mezger, president of the Lake Constance History Association, and the engineer Paul Fritz supported the undertaking. Prof. Robert Rudolf Schmidt from the University of Tübingen and his assistant Hans Reinerth provided the construction plans that they had created based on the findings of their excavations in Schussenried. The construction of the first two houses required 250,000 Reichsmarks. The financing was an early example of modern crowdfunding – anyone who wanted to could support the construction of the museum financially by subscribing to share certificates. In 1922 a museum association was founded. 100 eventful years followed, in which many crises were overcome: economic emergencies, political upheavals, war events and natural disasters. By the anniversary in 2022, 15.9 million people had visited the pile dwellings.

Between 1932 and 1937, competing Nazi leaders tried to take the popular museum into their “care”. Among them Reichsleiter Bormann, Minister Darré, Reichsführer SS Himmler, Minister Frick and Reichsleiter Rosenberg. In January 1938 the museum was one of the last in Germany to be aligned to the Reich Union for German Prehistory (Rosenberg Office).
