Demetrias was an ancient Greek city in Magnesia, near the modern city of Volos. It was founded by Demetrius Poliorcetes, and became the favourite residence of the kings of Macedon.
In 196 B.C., the Romans, victorious in the battle of Cynoscephalae over Philip V of Macedon in the previous year, took possession of Demetrias, but four years later the Aetolian League captured it by surprise. The Aetolians allied themselves with Antiochus III of the Seleucid Empire in the Roman–Syrian War.
Under Roman Emperor Constantine the Great (ruled 306–337) it became a Christian episcopal see and is now a titular see of the Catholic Church.
