Russia - Irkutsk

Irkutsk is a city and the administrative center of Irkutsk Oblast, Russia, and one of the largest cities in Siberia. The Irkut River, from which the town takes its name, is a smaller river that joins the Angara directly opposite the city. The main portion of the city is separated from several landmarks—the monastery, the fort and the port, as well as its suburbs—by another tributary, the Ida (or Ushakovka) River. The two main parts of Irkutsk are customarily referred to as the "left bank" and the "right bank", with respect to the flow of the Angara River.
