Patarei sea fortress Fortification

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.
