This is a statue at the stop for the ferry in Karamürsel (a town across the sea from Izmit) for wrestlers. Oil wrestling is a very popular sport, with its national centre in Edirne. And the Wikipedia has "Karamürsel is historically known as The Town of The Wrestlers". So ...
I do not recall if there was a bronze of some wrestlers and a set of plaques nearby. Probably the town produced two champions, that are displayed in portraits with their medals.
