Zhelezinskaya Fortress

Zhelezinskaya was one of a chain of fortified outposts raised along the Irtysh River in 1717 as the Russian Empire pushed its defensive Siberian frontier line into the Kazakh steppe. Together with other river forts of the era, it was intended to secure trade routes and garrison troops against raids while the empire extended control over the surrounding territory. The fortress predates the nearby Koryakovsky outpost, founded in 1720, which eventually grew into the city of Pavlodar, so Zhelezinskaya represents an earlier and separate link in that same line of 18th-century fortifications. Rather than developing into a major urban center itself, the site evolved into the settlement now known as Zhelezinka, seat of the Zhelezin District in Pavlodar Region. It stands today as a marker of the early stage of Russian military expansion along the Irtysh, predating the city that would come to dominate the region.
