Helenopolis

Helenopolis (Greek Ἑληνόπολις ) was an ancient city in Asia Minor landscape Bithynia (now Hersek in Turkey). She lay on the south side of the Gulf of Astacus and was first called Drepanon ( Δρέπανον ) or Latin Drepanum.

In honor of his mother Helena, who was probably born there, named Constantine the Great in the year 318, the city and sat thus in analogy to Konstantin Opel the sign that he regarded as his co-ruler with Helena. Konstantin often stayed in Helenopolis on - probably because of the warm baths - and was baptized here shortly before his death. In honor of the martyr Lucia did Constantine build a church.

A building boom seems to have used even under Justinian, who built more baths, aqueducts and other structures. Helenopolis was soon after his naming to a bishopric, whose most important carrier Palladius was well. The last bishop is known from the 9th century, then Helenopolis should have become increasingly insignificant.

Helenopolis in Bithynia is now a titular of the Roman Catholic Church. It belonged to the ecclesiastical province of Nicomedia. The titular is no longer occupied since 1967.
