Volos (170.000 inhabitants) is the capital of the district of Magnesia and it is situated at the edge of Pagassitikos bay, in proximity of the mountain Pelion or Pilion.
The city is built near the site of the ancient Iolkos, native place of Jason (mythology). The area of Volos, ancient Magnesia, is among the first inhabited areas in Greece. The settlements discovered in the nearby villages Sesklo and Dimini dating from the seventh millennium BC, while the cultural presence in place continues unbroken to this day. In the Mycenaean period dates the foundation of Iolcus, significant economic and cultural center of the region, directly linked with the famous legend of the Argonauts.
In the classical period (6th century BC.) flourished Pagasses, which were seaport of Feres.
In 293/92 BC the king of Macedonia Dimitrios Poliorketes founded on the peninsula, now called Pefkakia, the city Dimitrias, unifying Pagases with several neighboring villages. Dimitrias was a strong military base station of the Macedonians. At the same time developed into an important commercial center during the period from 217 to 168 BC The city was built according to the Ippodamius system and surrounded by massive walls. In the eastern part of town is the palace, south the market and west the theater. In the region are found many tombstones that give interesting facts about the economy, society and art of the time. In 197 BC Dimitrias fell to the Romans. Demetrias continued to flourish during the Roman conquest and from the 5th century. AD, became seat of bishop.
In 1204, after the sacking of Constantinople by the Franks, the city was given to Melissinos, famous Byzantine family. In the 14th century we meet for the first time the name of the place as Volos. In 1423 the Old Castle fell to the Turks. Then the Christian inhabitants began to leave the coastal areas and migrate to the heights of Pelion.
