Mediana is an important archeological site from the late Roman period, located in the eastern suburb of the Serbian city of Niš.

In 1979, Mediana was added to the Archaeological Sites of Exceptional Importance list, protected by the Republic of Serbia.

After Constantine's death in 337, the imperial residence in Mediana was used by several other emperors, either as a place of rest on their long journeys or during preparations for war.

During his two-month stay, Julian wrote long epistles to the Senate and to Athens, Corinth and other Greek towns, explaining his policy and seeking support.

The residence was erected on flat terrain, on an area which covers over 400,000 square metres, on a high bank, some distance from the river, at the foot of the hills which frame the Nišava Valley, near a thermal water source.

There was a street in the east-west direction which passed on the south side of the villa with peristyle and the granary located 150 metres from it.

The middle part of the audience hall is covered with a broad rectangular field with a geometric pattern, done in the manner of the finest artist.

The wide outer frame of the hexagon is covered with alternating stylized lotus flowers, and is underlined on the inner side, by a triple border.

There is a 10-meter height differential between the water tower site and the valley in which the Mediana buildings are located, providing a head for the fountains.

These individuals had artificially deformed skulls characteristic of Germanic peoples, and are presumed to have belonged to the Gothic cultural circle.

Genetic analysis suggested that these individuals were mostly of North Central European ancestry, with slight Iron Age steppe admixture, which is compatible with Germanic peoples.

[5] Haplogroup I1 is characteristic of Northern Europe and has not been found in the Balkans earlier, suggesting gene flow from the north.
