Kaunas Fortress

Kaunas Fortress is a ring of fortifications built around the city of Kaunas in what is now Lithuania during the period of Russian Imperial rule. Construction and expansion of the fortress system took place in the late 19th and early 20th centuries to fortify the strategic crossing of the Neman River.

The complex originally comprised multiple forts and supporting works arrayed around Kaunas as part of a defensive ring. One of the most visited components today is the Ninth Fort, which has been converted into a museum and memorial relating to wartime incarceration and mass killings in the 20th century.

Over the 20th century the fortress and its individual forts were repurposed by successive regimes for military, prison and transit uses; parts of the ring fell into disuse while others became sites of wartime atrocity remembrance. Restoration and museum work at selected forts interpret both the military architecture and the human history of the site.

The fortress works are located around Kaunas city in central Lithuania, forming a belt of fortifications that lie outside the urban core but within short driving distance of the city center.
