 Today, the beginnings of the town's industry, the now-defunct VTZ, have been recognized by the Serbian government as vital to Serbia's cultural heritage and, as of 2017, consists of 151 individual objects, of which 31 are protected as unique heritage, including the old foundry, the machine workshop, the chimney, the fire lookout tower, the railroad bridge over the Lepenica River, and the cartridge factory.Once known by its non-industrial residents as the 'Forbidden City' ("Zabranjeni Grad)," the complex is now open to the public.During World War I, Kragujevac again became the capital of Serbia (1914–1915), and the seat of many state institutions—the Supreme Army Command was housed within the court house building.
