Jonas Valley

Jonastal (Jonas Valley), situated in the Ilm-Kreis district in Germany between Crawinkel and Arnstadt and near to the town of Ohrdruf, was a scene of military construction under the National Socialist regime during the last years of the Second World War.

Thousands of prisoners from the Buchenwald concentration camp under the command of SS General Hans Kammler were forced to dig 25 tunnels into the surrounding mountain and the whole operation was performed under the strictest secrecy.

The exact aim of the operation remains uncertain although it is now believed to have been either a potential final headquarters for the führer Adolf Hitler, a military communications post or a possible center for V-2 rocket and Wunderwaffe weapon production and research.

She also claimed that she had heard another loud noise on March 12 at 10:15 p.m.[1] A book by Rainer Karlsch, Hitlers Bombe, published in 2005, alleges that Kurt Diebner's team tested some type of nuclear related device in Ohrdruf, which is very close to Jonastal.

Documents on which Karlsch's book is based shed light on the motivations of the German scientists working on the paths of nuclear reactors and isotope separation; the historian of science Mark Walker also published his analysis in 2005.
