Dubrovnik has opened to the public yet more proof of the wisdom of its glorious past. In the heart of this walled City, an expected, yet astonishing discovery has been revealed and expertly presented: a uniquely preserved industrial zone, a medieval foundry under the fort Minčeta from the late 15th century. Archaeological research and explorations within the Gornji Ugao Tower carried out during a three year period (2005 – 2008) resulted in the gradual discovery of a metallurgic foundry, which – much to the delight of the researchers, archaeologists who used archaeometry as „a forensic method“, historians, architects and conservationists – unearthed a true industrial miracle!
