Bomarsund, Military fortress ruins in Sund, Finland
Bomarsund is a fortress ruin located on the coast with walls arranged in a semicircular layout and multiple defensive positions built into the structure. The remains cover a large area with sections that once housed barracks, storage facilities, and observation posts.
The Russian Empire built this fortress between 1832 and 1854 as a strategic military position to control shipping routes in the Baltic Sea. During the Crimean War in 1854, allied forces destroyed the installation and it was never rebuilt afterward.
The fortress displays building techniques typical of Russian military design from the 1800s, visible in the thick stone walls and defensive structures scattered across the site. Visitors walking through can see how soldiers once occupied and used these spaces.
The site is accessible through marked walking paths that lead visitors around the ruins. A visitor center nearby provides information and orientation for those wanting to better understand what they are seeing.
Around 2,000 people once lived at this location, including soldiers and their families who formed a self-contained community. This population vanished quickly when the fortress was destroyed in 1854 and was never rebuilt.
