The name Komnina refers to the residents, who are considered descendants of Emperor Komninos of Trapezounta (Trabzon). Previously, Komnina was referred to as Paleohori in the Byzantine era, before it was destroyed after the conquest of region by the Ottoman Turks. During the Ottoman rule, Komnina was known as Utsena or Üçane, from the Turkish words üç(three) and ane(mother).

The first is the hill DELTA and the second is Ovon (Pontian for egg). Their existence is testified to by objects such as shells of vessels, copper coins, the base of a pillar, various marbles from buildings, two rings made of glass, a small cupbearer from Byzantine times and a marble bas-relief, in which is pictured a feminine form with tunic, helmet, spear and shield.
