Kola ostrog at the end of the XVII century: condition and armament

The article deals with a little-studied period in the history of the Kola Ostrog in the late 17th century. The Kola Ostrog was a typical wooden fortress in the Russian North, able to withstand a long siege, but at the end of the 17th century its military importance declined, which is confirmed by the general condition of the fortress. The author compares the Kola Ostrog with other fortresses of the Russian North, and also examines its fortifications and the dynamics of changes in armaments and ammunition.
