The Kodak fortress (; ) was a fort built in 1635 by the order of Władysław IV Vasa, ruler of the Polish–Lithuanian Commonwealth, and the Commonwealth's Sejm, on the Dnieper river near what would become the town of Stari Kodaky (now near the city of Dnipro in Ukraine). In 1711, according to the Treaty of the Pruth the fortress was destroyed by the Russians.
One of the Dnieper Rapids was called after the fortress.
History
It was constructed by Stanisław Koniecpolski to control Cossacks of the Zaporozhian Sich, to prevent Ukrainian peasants from joining forces with the Cossacks and to guard the southeastern corner of the Polish–Lithuanian Commonwealth. The Poles tried to establish order in that area, and commissioned French military cartographer and engineer Guillaume Le Vasseur de Beauplan to construct the fort.
After the Treaty of Pereyaslav in 1654, Kodak fortress was manned by the Cossacks. Peter I of Russia razed it in accordance with the terms of the Treaty of the Pruth with the Ottoman Empire in 1711. in Ukraine by establishing a quarry on the site in the early 1930s.
