Ust-Kamenogorsk Fortress, Military fortress at the confluence of Irtysh and Ulba rivers, Kazakhstan.
Ust-Kamenogorsk Fortress is a stone fortification at the confluence of the Irtysh and Ulba rivers that housed military barracks, a hospital, storerooms, and prison facilities within its defensive perimeter walls. The remaining structures still reveal how these different functional areas were organized within the defensive layout.
Commander Ivan Vasilievich Likharev built the fortress in 1720 under orders from Peter the Great while searching for gold deposits in the region. This establishment was part of Russia's strategy to strengthen its southern frontier in Siberia and establish control over new territories.
The fortress represents early Russian expansion into Central Asia and served as a military outpost that facilitated trade between Russia, Mongolia, and China. Visitors can still sense how this location functioned as a meeting point between different cultures and trade routes.
The site is relatively open for free exploration, allowing you to walk through and examine the remaining stone structures and their 18th-century Russian frontier architecture. It is best to visit during daylight hours and wear comfortable shoes, as the ground can be uneven in places.
This fortress marked the southernmost point of the Irtysh defensive line and later developed into the modern industrial city of Oskemen. The transformation from military outpost to populated city happened directly at this historical location.
