History of Suomenlinna Sea Fortress

This fortress has had quite the history. It was originally built by Sweden starting in 1748, primarily due to its excellent location in countering the rising Russian maritime threat during that time. The fortress over the next few decades was constructed and became operational, but was never complete. During the Russo-Swedish War from 1788-1790 and Russian pressure in the area thereafter, the fortress of Swedish recruits surrendered Sveaborg to the Russians in 1808. 

The Russians further fortified the fortress extensively, including the addition of artillery guns. Following the Russian Revolution in 1917 and subsequent independence of Finland, Suomenlinna was finally turned over to the Finns. Though not so much a fortress anymore, it is home to roughly 900 people. It briefly served as a prison camp during the Finnish Civil War. In 1973, most of the fortress was transferred to civilian administration, and in 1991, it was designated a UNESCO World Heritage Site. Today, Suomenlinna is a beloved cultural and historical landmark.

Key Architectural Features of Suomenlinna

One of the most impressive features is the dry dock, constructed in the 1750s to support Sweden’s archipelago fleet. It remains one of the oldest dry docks in the world and is still used for repairing traditional wooden ships.
