In the Werra valley near the border is one of the five soda factories of the GDR that once belonged to the powerful Solvay group. After the war, they moved the headquarters from Berneburg to Frankfurt, but some people loyal to the groups bosses remained to sabotage the production in the now nationally owned factory.
