The archeological and ethnographical complex Kazymsky (Yuilsky) burg is located in the tail of the river Von-Voshyugan of the left tributary of the river Kazym, downstream the river Kazym of the current village of Yuilsk. According to many investigators of Russian wooden architecture in Siberia, this monument is unique. It can be easily reconstructed due to partial preservation of the components lost. The “Khanty city” of Kazym was first mentioned in an annalistic source of the 16th century.
Stand-alone structures: two towers, a barn and a barrack cabin of the Yuilsky burg remained intact until the 1970’s. In 1969-1974 the archeologists and architects of the History and Archeology Institute, Siberian department, Russian Academy of Science explored the burg; after that the remnants of those structures were taken to Novosibirsk. At the same time, in the early 1970’s, roadside watchtowers, the voivode’s house, barracks and service structures (bathhouses, barns etc. were recorded within the burg area.
