Purpose. In this publication we present the materials from the Baraba Tatar structures complex, discovered at the multi-layered Sergino-2 site on the right bank of the Omi River near the Sergino village in Chanovsky District, Novosibirsk Region. During the excavation, three distinct cultural layers were identified. The oldest one is an Early Iron Age settlement, covered by a Late Middle Ages layer. The top layer represents a complex of modern times structures The purpose of this research is to introduce excavation results into scientific circulation.

Results. The structures complex of Baraba Tatar included a ground dwelling and two utility pits. The reconstruction shows a conical, triangular hut slightly sunk into the ground, with poles covered with layers of birch bark and supported by a central pillar. There were no traces of hearth within the buildings. Most likely, the building burned down – remains of collapsed walls and roofs, and fragments of burnt wood and birch bark were found on the second horizon. Due to the fire, the inhabitants were unable to take their belongings with them, so numerous fragments of ceramic vessels and iron products were discovered under the remains of the structure: knives, chisels, lances, staples, nails, etc. A glass bottle fragment and a rifle flint were also found.

Conclusion. The ceramic complex consists of molded vessels from the Baraba Tatar and Russian ceramic traditions. Animal bones found in the site suggest advanced cattle breeding practices. Most of the iron objects found at the site have analogues in Late Medieval and Russian sites in Siberia and European Russia. The findings demonstrate the interaction between the indigenous and Russian populations in the Baraba forest-steppe during the 18th and first half of the 19th centuries.
