Piast Canal

Karsibór (formerly German: Kaseburg or Caseburg) is an island in the Szczecin Lagoon, Poland, which was created by the cutting of the Piast Canal which separated it from the island of Usedom. The island was named after its largest village (now district of the town of Świnoujście). In 1880, the Kaiserfahrt (Piast Canal) channel was opened providing a water route with a depth of 10 metres (33 ft) connecting the lagoon with the Baltic Sea bypassing the eastern part of the Świna arm (Old Świna) of the Oder River, allowing large ships quicker and safer enter the lagoon and the seaport of Szczecin than on the natural river. The canal, approximately 12 km (7.5 mi) long and 10 metres (33 ft) deep, was dug by the German Empire between 1874 and 1880, during the reign of the first Kaiser Wilhelm (1797–1888) after whom it was named. After the defeat of Germany in World War II, under the terms of the Potsdam Agreement, in 1945 the region became part of Poland, which renamed the canal after the Piast dynasty. There is a memorial to the British pilots of the No. 617 Squadron RAF, who were shot down by Germany in April 1945.

The Świnoujście LNG terminal (also referred as Terminal LNG in Świnoujście, Polskie LNG Baltic LNG, or gazoport) is a liquefied natural gas (LNG) import terminal at Świnoujście, in the extreme north-west of Poland near the Polish-German border. The LNG terminal is operated by Polskie LNG S.A., a subsidiary of Gaz-System. The cornerstone for construction was laid on 23 March 2011 and it took its first LNG delivery on 11 December 2015. The terminal's regasification capacity is 5 billion cubic metres per annum (180 billion cubic feet per annum). The terminal is currently being expanded and once the expansion is complete in 2023, it will have a capacity of 7.5 billion cubic metres per annum (260 billion cubic feet per annum) and be able to satisfy about half of Poland's annual natural gas demand. Together with the 10 bcm of natural gas that Poland will (starting in 2023) receive annually from Norway via the Baltic Pipe natural gas pipeline, the Świnoujście LNG terminal will allow Poland to achieve its long-term goal of becoming fully independent of Russian natural gas, which had previously been the source of almost all of the country's natural gas.

Świnoujście is a major town at the end of the channel towards the Baltic Sea. The German Empire dammed and deepened the straits from 1874-1880 to create the Kaiserfahrt (Piast canal).

When Świnoujście became a port city, its inhabitants began to work on ships, leaving for long cruises. The wives waited for the sailors, who returned exhausted and aged. One of them, Alice, distraught by the appearance of her beloved Christopher, went to the seashore at night and cried. A mysterious voice told her to seek rescue in the windmill behind her, from which the old miller came out. He ordered Alice to come the next day with her husband; then he ordered to cover him with mud, take a bath in the sea and walk on the shore. A week later, he took him to a windmill. After some time, Alice's husband came out of the interior rejuvenated. The windmill was quickly visited by other sailors as well. However, when the old miller died, it turned out that no one knew the secrets of his treatments, and the mechanism of the windmill stopped. Despite this, people thirsty for rejuvenation continued to come – and still come today – to Świnoujście to cover themselves with mud, swim and walk.
