an episcopal see from the 3rd century on. Initially it was a suffragan of the Metropolis of Larissa, in the sway of the Patriarchate of Constantinople. Its first historically documented bishop was Leo, participant at the Council of Costantinople of 879-880 which rehabilitated Patriarch Photios I of Constantinople. It was raised to a metropolitan bishopric ca. 900, listed in the Notitia Episcopatuum attributed to the Byzantine emperor Leo VI (), as the penultimate metropolitan see under the Patriarchate of Constantinople with one suffragan see, the Diocese of Marmaritzana. A 10th-century seal holds the name of archbishop Cosmas, while the Metropolitan Nicholas signed a synodal decree from Patriarch Sisinius II of Constantinople around 997. Until the 13th century, the city is most notable as an ecclesiastical centre. In the 12th century it had three suffragans: Marmaritzana (again) plus Diocese of Hagia and Diocese of Bela, but in the 13th century, it was reduced again to Marmaritzana alone, before ceding this too to the Archdiocese of Lamia (Zetounion), probably after 1318. At the turn of the 13th century, its bishop, Euthymios Malakes, was a correspondent of the metropolitan of Athens, Michael Choniates. After the Fourth Crusade, the city was made a Latin rite archdiocese, the Latin Archbishopric of Neopatras. The see was suppressed after the Greek reconquest, but restored when the Catalans established the Duchy of Neopatras in 1319, and remained active until the Ottoman conquest at the turn of the 15th century. In 1933, it was restored as a Catholic titular see.

He observed many large quadrangular blocks of stones and foundations of ancient walls on the heights, as well as in the buildings of the town. In the metropolitan church he noticed a handsome shaft of white marble, and on the outside of the wall an inscription in small characters of the best times. He also discovered an inscription on a broken block of white marble, lying under a plane-tree near a fountain in the Jewish cemetery.
