Amphipolis was an important ancient Greek polis, and later a Roman city, whose large remains can still be seen. It gave its name to the modern municipality of Amphipoli, in the Serres regional unit of northern Greece.
Amphipolis was originally a colony of ancient Athenians and was the site of the battle between the Spartans and Athenians in 422 BC. It was later the place where Alexander the Great prepared for campaigns leading to his invasion of Asia in 335 BC. Alexander's three finest admirals, Nearchus, Androsthenes and Laomedon, resided in Amphipolis. After Alexander's death, his wife Roxana and their son Alexander IV were imprisoned and murdered there in 311 BC.
