Hierocaesarea or Hierokaisareia, from the Greek for 'sacred' and the Latin for 'Caesar's', also known as Hieracome or Hierakome, was a town and bishopric in the late Roman province of Lydia, the metropolitan see of which was Sardis.
It was inhabited during Hellenistic, Roman, and Byzantine times.
[2] Judging from its coins, it worshipped the goddess Artemis Persica.
Its site is located between Sazoba and Kumkuyucak in Asiatic Turkey.
[1][3] It is mentioned as an episcopal see in all the Notitiae Episcopatuum until the 12th or 13th century,[4] but only three of its bishops are known: The see remains a (vacant) titular see in the Roman Catholic Church, with nominal bishops appointed.
