History
Antiquity
The modern town is built on the ruins of the ancient city of Pyrasos, and is associated with the nearby city ofThessalian or Phthiotic Thebes, near the modern village of Mikrothivai. Homer mentions Pyrasos in his list of ships together with Phylace and Itona, which belonged to the kingdom of Protesilaus. According to Strabo, who discusses its topography, "well-harboured Pyrasos" was 20 stadia from Phthiotic Thebes. Pyrasos is scarcely known from historical sources, except that it was an active harbour and featured a famous temple of Demeter and Kore, after which the harbour was later known as Demetrion. The only excavation which took place on the hill of Magoula, the old acropolis, southeast of Nea Anchialos, proves that the site was peopled since the earliest Neolithic period by fishermen and agriculturalists. Archaeologically, the remains of Pyrasos are scant, and the city is barely known in historical times. An arm from an oversized statue, which came into light in 1965, was attributed to Demeter. Possibly the most identical finding is a small fragment of an ancient epigraph, discovered in the debris of the big Basilica D with the name Pyrasos, confirming the location of the city. In the late 4th century BC, Pyrasos was joined with the neighbouring cities of Phylake and Phthiotic Thebes. The new conurbation took the name of Phthiotic or Thessalian Thebes. The city remained prosperous under Roman rule, but it was moved from the inland site of the old Phthiotic Thebes back to Pyrasos near the sea. The city's prosperity from the 4th through the 6th centuries is attested by the number of its Early Christian monuments, but was brought to an end in a great fire in the late 7th century that destroyed the city. The city was rebuilt and apparently continued to be of some note in the early Byzantine period—its bishop is last mentioned in the 8th/9th century—but never recovered and was eventually eclipsed by the nearby port city of Halmyros.
