In the Neretva Delta in the south, there was important Hellenistic influence of the Illyrian Daors tribe. Their capital was ''Daorson'' in Ošanići near Stolac. Daorson in the 4th century BCE was surrounded by megalithic, 5 m high stonewalls (as large as those of Mycenae in Greece), composed of large trapezoid stone blocks. Daors made unique bronze coins and sculptures.
