THE LAST FORTRESS OF THE KHAN KUCHUM ON IRTYSH
In this article we are talking about one of the strengthened complexes of the Siberian khanate - the Tunusky town, which was located on right-bank inflow of Irtysh - the Tara, approximately in 50 km from its valley. The river Tara flows in the width direction and serves as border between forest-steppe and taiga zones of Western Siberia, therefore almost entire period of ancient and medieval history it was border between the forest and steppe population. The Tunusky town has been built in the seventies years of 16th century together with several towns, which have made the defensive line, which protected lands of the khanate from the Khanty population. At the same time these towns were the centers for collecting a yasak from the population living here. During 2003-2006 years the town was investigated by archaeological expedition of Omsk branch of Institute of archeology and ethnography of the Siberian Branch of the Russian Academy of Science under my management. Materials of researches have formed the basis of this composition.
