Nikolai, an Alaskan town, is a quiet place where the northern lights often appear.

Nikolayevsk was frequently visited by river traders during the late 19th century, who brought furs and tea down the Amur.

Nikolayev visited the old library to research his family's roots.

During our expedition, we stopped in Nikolayevsk-na-Amure to study the town's unique Amur River heritage.

Nikolayevsk-on-Amur grew into an important river port during the 19th century.
