Fort VII in Kaliningrad, Military fort in Kaliningrad, Russia.

Fort VII is a military fortification in Kaliningrad with sturdy stone walls, defensive bastions, and underground passages for troop movements. The complex connects multiple levels and chambers that were designed for various military purposes.

Built between 1887 and 1890, Fort VII was named after the Dukes of Holstein, many of whom served Prussia. It guarded the Königsberg Canal and the Pregolya River from the west. On 10 April 1945, after Königsberg's garrison had capitulated, a assault group of the 24th Guards Division took the fort, capturing 250 soldiers and officers.

The fort displays late 19th century Prussian military engineering through its construction and placement within the fortification network. You can see in the walls and bastions how military planners of that era approached defensive design.

Access to the fort is closed, so it cannot be entered or toured; the site was used as a warehouse for the Baltic Fleet repair plant. It stands on the right bank of the Pregolya where the river meets the Kaliningrad Bay, west of the Pregolsky settlement. The structure can only be viewed from outside.

The fort was stormed on 10 April 1945, after Königsberg's garrison had already capitulated, by a assault group of the 24th Guards Division. Lieutenant I. A. Patrushev's self-propelled guns fired point-blank from 100–150 metres to silence the machine-gun nests, after which Major Timoshenko's 84th Guards Regiment took the fort with almost no losses: 250 soldiers and officers were captured.
