Exhibition devoted to the Por-Bazhyn fortress in Tuva in the south of Siberia, in close vicinity of the Russian-Mongolian border, on the island, situated on a high–mountain lake, will open in the State East Museum in Moscow on November 7 and will close on 25. This summer a large scale expedition excavated the remnants of the Por-Bazhyn Fortress that was built in the middle of the 8th century. Translated from the Tuvin language Por–Bazhin means an “earthenware house”. The expedition’s leader Professor Viktor Solovyov believes that it was a “summer residence' of the Uyghur Kagan. Most of its facilities were not inhabited rooms as they had a through passage. A facility in Tuva is a monument with complex architecture: there’s a labyrinth of buildings inside a regular rectangle.
