The fortified palatial complex in Gamzigrad (Romuliana) represents a remarkable example of architecture and art in the area of the Balkans during the Tetrarchy period, created during the short reign of its owner and commissioner – Emperor Galerius (305-311). Remains of a complex with buildings of official, cult and residential character, protected by ramparts, were discovered in Romuliana, in a place for life and apotheosis of the Emperor, once he would have stepped down from the throne. The complex had opulent architectural decorations: rooms and open spaces were decorated with sculptures, walls with frescos and mosaics, and floors with polychrome mosaics.
