Hadriani ad Olympum

Hadriani ad Olympum, also known simply as Hadriani or Hadrianoi, was a town of ancient Bithynia, not far from the western bank of the river Rhyndacus in what is now northwestern Turkey. As its name indicates, it was built by the Roman emperor Hadrian, and for this reason it did not exist in the time of the geographer Ptolemy. It was situated on a spur of Mount Olympus, from which it also took its name. The town was the birthplace of the rhetorician Aelius Aristides, born in 117 AD. Christian ecclesiastical writers record it as the seat of a bishop in the Hellespontine province. It is no longer a residential see but remains a titular see of the Roman Catholic Church.
