In the top of the mountain Mavro Pouli is a small cave, called the Crypt of Kara-Ali'. Traces of the walls of two fortresses and settlements exist in the vicinity of Komninos. 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. ==References==
