The Seaplane Harbour (Lennusadam) is a maritime museum located in the Kalamaja district of Tallinn, Estonia. The museum is housed within historic seaplane hangars that were originally constructed between 1916 and 1917 as part of the Peter the Great's Naval Fortress, a defensive network commissioned by the Russian Empire to protect the approaches to Saint Petersburg.
The structure is architecturally significant for its pioneering use of thin-shell concrete domes, which were among the first of their kind in the world. Today, the facility serves as the primary maritime museum of the Estonian Maritime Museum, housing a diverse collection of naval artifacts, including the 1936 submarine Lembit and various historic vessels, displayed within a restored industrial environment.

Imperial Origins
1916-1917The hangars were commissioned by the Russian Imperial Navy as part of the coastal defense system for Tallinn, then known as Reval. The design utilized innovative reinforced concrete shell construction, allowing for a vast, column-free interior space.
Estonian Independence and Soviet Era
1918-1991Following Estonian independence in 1918, the hangars were used by the Estonian Air Force. During the Soviet occupation, the site was utilized by the Soviet Navy, leading to a period of neglect and structural deterioration toward the end of the 20th century.
Restoration and Museum Opening
2010-2012A comprehensive restoration project began in 2010 to stabilize the concrete domes and repurpose the hangars for public use. The museum officially opened in 2012, receiving international recognition for its architectural preservation and exhibition design.
Cultural Significance
The Seaplane Harbour is a landmark of Estonian industrial heritage and a symbol of the country's maritime identity. It represents the transition of Tallinn from a strategic military outpost to a modern cultural hub, preserving the technical ingenuity of early 20th-century engineering.
Interpretive Notes
Scholarly debates and areas of uncertainty
Discussions among architectural historians often focus on the influence of the Danish engineering firm Christiani & Nielsen in the development of the thin-shell concrete technique used at the site, and the extent to which the original design was influenced by contemporary European hangar projects.
