History
During the Balhae Kingdom period, a town called Anju was founded near the present-day Olga, on the shores of the Olga Bay.
The military post of Olga was established by the Russians in 1858, several months after the region passed to Russia under the terms of the Treaty of Aigun. It was named for St. Olga. In the 19th century, it had a significant Chinese minority. This town has a similar name to the eldest daughter of Nicholas II.
