A place steeped in history, not so positive. Actually "only" a potash shaft, misused as an army munition during the Nazi era. "Around March 16, 1945, the coffins of Paul von Hindenburgs and his wife Gertrud as well as the kings Friedrich Wilhelm I and Friedrich II of Prussia were moved into the shaft, as well as the flags and standards of the German army from 1914-1918, the files of the Federal Foreign Office, the Kassel Cadastral Office, pictures from Prussian state museums, the Sanssouci library, the Prussian crown jewels, valuable porcelain and 271 paintings. A wall was also built against these "treasures". " de.wikipedia.org/wiki/Nationalsozialismus_im_Eichsfeld#Heeresmunitionsanstalt_Bernterode_%28Schacht%29
