Mediana is an important archeological site from the late Roman period, located in the eastern suburb of the Serbian city of Niš. It represents a luxurious residence with a highly organised economy. Excavations have revealed a villa with peristyle, thermae, granary and water tower. The residence dates to the reign of Constantine the Great 306 to 337. Although Roman artifacts can be found scattered all over the area of present-day Niš, Mediana represents the best-preserved part of Roman Naissus. In 1979, Mediana was added to the Archaeological Sites of Exceptional Importance list, protected by the Republic of Serbia.
