Northwest of Alexandroupolis, near the river Evros and a short distance from Feres, was built the ancient city of Doriskos. Although small in size, its strategic location in "Saragia", on a low hill overlooking the rich plain of Evros, made it an important reference point for several historical events.
In 513 BC, King Darius I established a Persian garrison to campaign against the Scythians, while shortly afterwards (480 BC) Xerxes, his successor, stationed himself at Doriscos to repair the fleet, refuel and count his troops. Doriscos subsequently participated in the Athenian Alliance, then became a conquest of the Macedonian kings and then Ptolemy.
The new settlement of Doriscos was built 1-2 km from the ancient city. On the hill today you can see ruins of the ancient wall, tumuli and tombs, while several findings (vases, ancient coins that "testify" to the trade relations of Doriskos with several cities of antiquity) have been transferred to museum collections.
