Daorson (Ancient Greek Δαορσών) was the capital of a Hellenised Illyrian tribe called the Daorsi (Ancient Greek Δαόριζοι, Δαούρσιοι; Latin Daorsei). The Daorsi lived in the valley of the Neretva River between 300 BC and 50 BC.
Daorson was built around a central fort or acropolis, surrounded by cyclopean walls made of huge stone blocks (similar to those in Mycenae, in Greece). The acropolis would have housed all of the important administrative, public and religious buildings. The defensive wall extending from southwest to northeast was 65 metres long, 4.2 metres wide, and from 4.5 to 7.5 metres high with doors and towers on both sides. The Daorsi used the Greek language and alphabet and kept trading relations with the Greeks.
A megalithic wall, erected following the lie of the land, has been dated to the 4th century BCE, when both towers were probably built following the construction of the wall.
