Modern Volos is built on the area of the ancient cities of Demetrias , Pagasae and Iolcos . Demetrias was established by Demetrius Poliorcetes, King of Macedon . Iolkos, Iolcos or Iolcus , was the homeland of mythological hero Jason , who boarded the ship Argo accompanied by the Argonauts and sailed in quest of the Golden Fleece.
To the west of Volos lie the Neolithic settlements of Dimini , with a ruined acropolis , walls, and two beehive tombs dating to between 4000-1200 BC, Sesklo , with the remains of the oldest acropolis in Greece (6000 BC), and also the foundations of a palace and mansions, among its most characteristic examples of Neolithic civilisation. Mycenaean settlements have also been discovered in Volos unearthing, at the Kastron of Palaia Hill, tablets bearing Mycenaean Greek inscriptions, written in Linear B .
Volos is the administrative centre of the Magnesia regional unit. Many of the city domains are separated through natural barricades, such as rivers.
Three main rivers/mountain torrents all rise from mount Pelion (1651m), crossing the city to create a unique urban geography, before ending in the Pagasetic Gulf flowing west. The Anavros river, famous for Jason's pass, divides the Nea Demetriada district from the rest of the urban area. Krausidonas is the major river passing through the city, and constitutes the natural lung of the urbanized area of Volos, as well as the boundary between the major municipalities of the metropolitan city, the municipalities of Volos and Nea Ionia. The third torrent, Xirias (Ξηριάς), is the largest of the metropolitan urban area of Volos, and passes through the Nea Ionia municipal area.
