In 1984, the planned construction of a power plant near Hainburg threatened to destroy the last remaining long section of the free-flowing Danube and its riparian forests. Calls to action by all conservation and environmental groups led to nationwide protests. As the operators of the power plant were to about to begin construction, a peaceful occupation of the wetland forests at Stopfenreuth by thousands of people of all ages and social classes took place - the legendary "Hainburger Wetlands Sit-In". After many unsuccessful attempts by the police in December 1984 to clear the area of protesters, the federal government ordered a cessation of activities in order to reconsider the situation.
