Stobi

Stobi or Stoboi, was an ancient town of Paeonia, later conquered by Macedon, and finally turned into the capital of the Roman province of Macedonia Salutaris. It is located near Gradsko, North Macedonia, on the main road that leads from the Danube to the Aegean Sea and is considered by many to be the most famous archaeological site in North Macedonia. Stobi was built where the Erigon joins the Axios, making it strategically important as a center for both trade and warfare.
