Amphipolis

Amphipolis (Greek: Αμφίπολη) was an ancient Greek polis and later Roman city in Macedonia, Greece, founded as an Athenian colony in 438/437 BC on the strategic Strymon River near valuable gold mines at Pangaion [1][2]. The city controlled key trade routes between Thrace and the Aegean, making it a major military prize—it was the site of a pivotal battle between Sparta and Athens in 422 BC, and later Alexander the Great used it as a staging point for his Asian campaigns [1]. Today, extensive archaeological remains survive, with finds displayed in the Archaeological Museum of Amphipolis and Archaeological Museum of Kavala [2].
