Patarei Sea Fortress, Maritime fortification complex in Kalamaja, Estonia.
The fortress spans over 16,000 square meters along the Baltic Sea coast, featuring curved walls, a caponier, barracks, and officers' quarters.
Emperor Nicholas I ordered the construction of this naval defense structure in 1828, which was completed in 1840 to protect Baltic borders.
The fortress operates as a museum space with an exhibition titled 'Communism is a Prison' covering 1,200 square meters in the eastern wing.
The location at Kalaranna 28 in Tallinn provides visitors access to both historical exhibits and Baltic Sea views throughout the summer months.
The structure transitioned from a maritime fortress to soldiers' barracks in 1864, then served as a state prison from 1920 until 2002.
