Fort VIII in Kaliningrad, Military fortress in Shosseinoye, Russia.

Fort VIII, named after the Prussian king Frederick I, is an elongated hexagonal fort measuring 205 by 135 metres, surrounded along its perimeter by a dry moat. Its rooms and inner courtyards are laid out symmetrically around the central poterne, and its gorge caponier was built of brick. It stands near the crossing of Bolshaya Okruzhnaya Street and Kaliningradskoye Shosse.

Fort VIII was built in 1882 and named after the Prussian king Frederick I, forming part of the defensive ring around Königsberg. In April 1945 it guarded the railway and road to Elbląg; on 6 April it was blockaded by the 243rd Guards Rifle Regiment, and after a short assault led by Senior Lieutenant P. A. Bysov it capitulated at 11 a.m. on 7 April, with 150 German soldiers and officers taken prisoner. In 2007 it was designated a regional cultural heritage site.

The fort is tied to the Prussian past of the city and shows how military construction shaped the urban landscape. Today it serves as a reminder of when the region was under German influence and played an important role in European defense history.

The fort is accessible by foot through the neighborhood streets and has marked paths and visitor entrances. Comfortable shoes are recommended since you will walk over uneven ground and stairs.

The fort's gorge caponier, the rear defensive work facing the attacker's approach, was built of brick. The fort was named after King Frederick I of Prussia, and its elongated hexagon measures 205 by 135 metres, ringed by a dry moat.
