The ancient city of Stobi, lying in a fertile valley just a few minutes of the central north-south highway contains buildings such as the 2nd century amphitheatre, The Theodosia palace, and early Christian ruins with extensive and ornate mosaic floors. As a city, Stobi is first mentioned in documents from the 4th century B.C.E., and it experienced its biggest period of growt from the 3rd-4th century C.E.
Famous for its dazzling mosaics, ancient theater and Roman baths, Heraclea is the most vividly preserved city from the Ancient Macedonian empire surviving in the country. Founded in the 4th century B.C.E. and conquered by the Romans two centuries later, it was built on the Via Egnatia and became one of the key stations on this trading route. From the 4th-6th centuries C.E. Heraclea also had an Episcopal seat. The first excavations were done before the First World War, but only since then have the full glories of the ancient city been revealed. Beautiful Roman baths, the Episcopal church and baptistery, a Jewish temple, portico and a Roman theater now used for summer concerts and theater shows all survive in excellent condition.
