The 1960s are sometimes considered the ‘Golden Age of the GDR’: a relatively prosperous decade of increased personal freedoms and moderate economic success. With the expansion of the local ironworks came the need for two new living complexes, represented in the model above by the white blocks in the top right (directly above the large oval, which was to be the city stadium). The distancing of the four original living complexes from the new developments constituted a physical rupture in the overall plan of the city, literally spacing those housed in the more expensive center of the community from their (often younger) fellow residents in the sixth and seventh “plattenbau” or prefabricated panel buildings.
