Балтийск бұғазы: тарихы мен маңызы

Strait in Kaliningrad Oblast, Russia

The Strait of Baltiysk (Балтийский пролив, Cieśnina Piławska, Pillauer Tief) is a strait enabling passage from the Baltic Sea into the brackish Vistula Lagoon, located in Kaliningrad Oblast, Russia. The constructed strait separates the Vistula Spit from the peninsula (called Pillau Peninsula in Russia: Пиллауский полуостров, after the Pillau Fortress) which was part of the Vistula Spit in the 15th century and now is part of Sambian Peninsula.

The strait is the shipping connection from the high sea to the important Russian ports of Baltiysk and Kaliningrad in the northeastern lagoon, as well as to the Polish ports of Elbląg, Braniewo, Tolkmicko, Frombork, Sztutowo, Krynica Morska, and Nowa Pasłęka in the southeastern lagoon. On 17 September 2022, Poland opened a new canal through the Vistula Spit, which will allow ships to enter the Polish port of Elbląg without passing through the Strait of Baltiysk in Russia's Kaliningrad region. Despite the law since the 1990s Russia periodically blocks navigation via the strait to Polish ports. Since 2006, Poland has considered digging another canal across the Vistula Spit in order to circumvent this restriction. The Vistula Spit canal started construction in 2019 and opened in 2022.

In 1497 a storm surge dug a new gat, then called the Neues [Pillauer] Tief or Pillauer Seetief (New [Pillau] Deep, Pillau Sea Deep), through the Vistula Spit. In 1510 another storm surge widened and deepened that gat to navigability. It measured in length and in width. In 1626 King Gustavus Adolphus of Sweden landed with 37 ships next to the gat, at a spot already slightly fortified, transforming it into the Pillau Fortress, and holding it for ten years (till the Treaty of Stuhmsdorf), also in order to pressure his brother in law George William, Duke of Prussia and Elector of Brandenburg, to support him in the Polish–Swedish War and the Thirty Years' War. The Swedes extended the adjacent Pillau village and built its first place of worship, a Lutheran church. In 1638 the Duke moved his residence to the close by ducal capital Königsberg in Prussia. In the 1960s the gat was expanded and now it measures in width and in depth.
