Vladivostok Fortress Museum encompasses one of the world's largest fortification systems with 44 unique objects spread across the Muravyov-Amursky Peninsula and Russky Island. Built in the late 19th and early 20th centuries to protect the Russian Pacific port, these fortifications are considered masterworks of military engineering. The visitor center offers interactive exhibitions and guided tours in multiple languages through underground galleries, tunnels, and forts. Some sites require adventurous exploration through wild nature. A UNESCO World Heritage candidate, the fortress offers tours ranging from 1 to 8 hours covering different fortification clusters
