Prusias ad Hypium was a city in ancient Bithynia, and afterwards in the late Roman province of Honorias, and a bishopric that was a suffragan of Claudiopolis in Honoriade. Before its conquest by King Prusias I of Bithynia it was named Cierus or Kieros (Ancient Greek: Κίερος). Photius writes that it was called Kieros, from the river which flows by it.[1]

It site was near Konuralp, Düzce Province, Turkey.[2][3]


Memnon of Heraclea says that King Prusias I of Bithynia (237-192 B.C.) captured from the Heracleans the town of Kieros, united it to his dominions and changed its name to Prusias.[4] Pliny[5] and Ptolemy[6] merely mention it, one below Mt. Hypius, the other near the River Hypius.


Several of its bishops are known:

  • George (not Hesychius, as Le Quien says), 325;
  • Olympus in 451;
  • Dometius in 681;
  • Theophilus in 787;
  • Constantine in 869;
  • Leo in 879;
  • St. Paul, martyred by the iconoclasts in the ninth century.[7]

It is not known when this see disappeared; it still existed in the tenth century.[8]

No longer the seat of a residential bishop, it remains a titular see of the Roman Catholic Church.[9]
