Patarei Sea Fortress and Prison
Patarei Sea Fortress and Prison is a sprawling 19th-century coastal complex located on the shore of Tallinn Bay. Originally constructed as a Tsarist naval artillery battery, it was transformed into a high-security prison in 1920, where thousands endured oppressive incarceration, torture, and executions under Soviet and Nazi regimes, leaving behind a dark atmosphere charged with haunting prison lore.
