To a question on the location first Achinsk ostrog (fortress)

In the publication of O. A. Igoshin in the almanac «Yenisei province» concerning an establishment of a place of construction first Achinsk ostrog (fortress) 1641 is made the assumption, that he could be created only at lake Fyrkal on a coast of the small river Fyrkalka in north Khakassia [Игошин, 2007]. In opinion of the author given microarea in a valley river Bely Iyus and lake Fyrkal is most suitable for creation of Russian fortress. However survey, carried out by us, of district has shown, that here are absent both necessary for creation fortress of a condition, and traces of such structure. Besides proceeding from the detailed analysis of the messages of written sources, it is visible, that fortress was put much to the north, in Achinsk county (volost), under which name he and has received the name. It does unpromising archaeological searches it in a valley of average current of the river Bely Iyus.
