Patarei Prison is a building complex in Kalamaja district of Tallinn, Estonia. The premises cover approximately four hectares of a former sea fortress and prison, located on the shore of Tallinn Bay.
The fort was built from 1830–1837 as part of the fortifications for the tsarist Russian state. The building order was given by emperor Nicholas I. In 1864, Tallinn was removed from Russian Empire’s list of fortresses due to Russia’s defeat in the Crimean War, and the fort was converted into barracks.
The Republic of Estonia, which declared independence in 1918, reconstructed it as a prison after World War I. In 1919, the fort's main function became a prison, lasting until 2005.
For Estonians, Patarei is one of the most prominent symbols of Soviet and Nazi political terror.
In 2018, the Estonian Institute of Historical Memory launched preparations to establish a museum of crimes of communism and an accompanying international research centre in Tallinn. The museum is planned to an approximately 5,000 square meter area in the eastern part of the building and is scheduled to open in 2025.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
