The Baltic Sea port of Paldiski situated on the Pakri Peninsula of north-western Estonia. It was once the Swedish Empire settlement known as Rågervik and became a naval base of the Russian Empire in the 18th century. The Russians renamed it Балтийский Порт ("Baltiyskiy Port", i.e. Baltic Port, German: Baltisch-Port) in 1762, and the Estonian pronunciation, Paldiski, became the official name in 1933. In 1962, Paldiski became a Soviet Navy nuclear submarine training centre, until the Russians left it in 1995.
