Discover more about Suomenlinna

Suomenlinna, a remarkable sea fortress, sprawls across six islands just a short ferry ride from Helsinki's Market Square. This UNESCO World Heritage site boasts a rich history, having served as a defense for three different nations: Sweden, Russia, and Finland. Construction began in 1748 when Finland was part of Sweden, with Admiral Augustin Ehrensvärd overseeing the project. Originally named Sveaborg (Fortress of Sweden), it was intended to protect against Russian expansion. In 1808, the fortress fell to Russian forces, marking the end of Swedish rule in Finland. The Russians expanded the fortress, using it as a naval base. Following Finland's independence in 1917, it was renamed Suomenlinna (Fortress of Finland). Today, Suomenlinna is a vibrant district of Helsinki, home to around 800 residents and a workplace for about 400 people. Visitors can explore the fortress's extensive fortifications, museums, and historical sites. Key attractions include the Suomenlinna Museum, which details the fortress's history, and the Ehrensvärd Museum, showcasing the life of the fortress's founder. The island also features the Submarine Vesikko, offering a glimpse into naval warfare, and the Suomenlinna Church, which doubles as a lighthouse. With its unique blend of history, culture, and natural beauty, Suomenlinna offers a captivating experience for tourists and locals alike. Note that Suomenlinna can be challenging to navigate for those with impaired mobility due to cobblestone streets and uneven terrain.
