About
Vladivostok Fortress is a system of fortifications built from 1889 to 1918 in Vladivostok, Russia, and the surrounding area.
During construction, lessons from the Russo-Japanese War were taken into account, so that this is the most fortified of all the fortresses built at this time. Construction of the fortress was halted with the structure about 2/3 complete, due to the disruptive influence of the First World War and the October Revolution.
