The harbour overlooks tiny Zeytinlik island where there is a research station devoted to olives.

According to the Ottoman General Census of 1881/82–1893, the kaza of Erdek had a total population of 33,007, consisting of 29,165 Greeks, 3,070 Muslims, 300 Jews, 18 Armenians and 454 foreign citizens.
