Stobi The ancient city of Stobi, lying in a fertile valley just a few minutes off the central north-south highway that connects Macedonia with Greece, was a vital trade route in its day. This crossroad of ancient civilizations has left a rich legacy of antique theaters, palace ruins, brightly-colored mosaics and religious relics for visitors today to enjoy. As a city, Stobi is first mentioned in documents from the 2nd century B.C.E. However, archaeologists believe that the town had been inhabited from at least 400 years earlier. Stobi became a rich and prosperous city due to its location on the crossroads of important trade routes. It experienced its biggest period of growth from the 3rd-4th centuries C.E. The archaeological site (located just 3 km or 1.8 miles from the Gradsko exit on Highway E-75) offers sweeping views of the central Macedonian plain and contains buildings such as the 2nd century amphitheatre, the Theodosia palace, and early Christian ruins with extensive and ornate mosaic floors.
