The fort was originally designed as a 'Type F' battery, emphasizing dispersed artillery positions rather than a single concentrated castle wall.
During 1920, the fort functioned as an internment camp for soldiers of the Ukrainian People's Army, many of whom were held here following the Polish-Soviet War.
The site features a significant amount of original brick masonry that showcases the rapid fortification expansion strategies of the Russian Empire in the late 1800s.
It is part of a wider network of forts surrounding the Zegrze Fortress, which was intended to control the Narew and Bug river crossings.
Fort Beniaminów is a 19th-century artillery fortification forming part of the outer ring of the Zegrze Fortress complex. It was constructed by the Russian Imperial Army between 1887 and 1909 to protect the Warsaw metropolitan area. The structure is an earth-and-brick fortress featuring a pentagonal plan and a series of underground shelters known as bomb-proof barracks. During the interwar period, the facility served as an internment camp for Ukrainian soldiers and later as a military training site. Much of the original structure remains unrestored, providing a raw look at late-Tsarist defensive military architecture. It is currently recognized as a historical landmark situated within the administrative boundaries of Beniaminów.
The main entrance gate and the remaining earthen ramparts offer the best architectural perspective.
