The Bunker "city" in Wünsdorf, with over 100 years of history, was the operations center of the Wehrmacht in the second world war.
The army of the Soviet Union was stationed there almost 50 years and the plant was equipped for the event of an atomic war.
Since the withdrawal of the Russians in 1994, the immensely large bunker system has been largely left to itself - the duration of the "natural" decay process is estimated to be at least 1,000 years.
In 1998, the Bücherstadt-Tourismus GmbH, based in Zossen, took over the administration of the facilities.
Displaced was the theme of the festival that the association Schlachten, at that time still a local village 'Heimatverein e.V.' association, in 2015 organized a six week long festival in the Mendelssohnhalle in Luckenwalde.
In 2017, the new association "Die Schlachten" ("The Battles") is creating a new festival, which is about this underground and historically charged place of security!
