Submarine, Icebreaker, Oldest sea wreck

A former naval fortress located in the Kalamaja district of Tallinn.

Designed by military engineers Étienne-Louis Boullée and Claude-Nicolas Ledoux, Patarei was commissioned in 1829 by Russian Emperor Nicholas I. The complex was opened in 1840, but this did not mean that construction work was complete. The fortress underwent renovations: there were fears that the British and French would attack from the Baltic Sea after the outbreak of the Crimean War in 1853. This did indeed come to pass, but it did not escalate into large-scale warfare. Only a few shots were fired from Patarei. As a result of the adoption of explosive projectile, Patarei was decommissioned as a fortress in 1858 and was thereafter used as barracks. During the era of Estonia’s independence, Patarei was turned into a prison, which operated until 2002. It had also been used as a prison during the German and Soviet occupations. The atrocities committed there by those regimes made the place infamous among the population. The architecturally prominent building, which covers four hectares, is now home to an exhibition entitled ‘Communism is Prison’, which shines the spotlight on communist ideology, communist crimes and the history of the building. Renovations of this remarkable architectural wonder covering four hectares began in 2020. By 2026 Patarei shall be an integrated urban landscape complete with commercial space, living quarters and leisure options. The original prison interior and exercise yards shall be preserved in the eastern wing of the building. Already there's an exhibition on the communist ideology and atrocities and the history of the building covering close to 1200 square metres.

The Seaplane Harbour is situated on the water’s edge in the Kalamaja district of Tallinn.

It was commissioned during World War I by Russian Emperor Nicholas II as part of Peter the Great's Naval Fortress. The museum, based in the historic seaplane hangar, has around 200 original exhibits on display: the submarine Lembit, the 100-year-old icebreaker Suur Tõll, the seaplane Short 184, the oldest Estonian shipwreck, mines, cannons and more. Temporary exhibitions complement the main exhibition. The seaplane hangar is architecturally unique: its domed roof was one of the first thin concrete shell structures of its kind.

The museum’s programmes and materials for individual visits are fun and educational for adults and children alike.
