History of the Sobieszewo Island

Genesis of Sobieszewska Island formation is inseparably connected with Vistula, and mainly processes taking place in its delta. A dynamic activity of the river, waterside changes caused by sea impact, led to creating a sandbar. In this belt, the area of today’s Island was found, before forming.

The environmental activity of nature forces and human’s interference in a hydrographic system of Vistula influence the island’s creation. Till 1840, Vistula went to Gdańsk Bay through its main stream in Gdańsk. However, this stream, in certain moment, appeared to be insufficient to give up the excess of waters to the sea. That is why, during the night from 31st January to 1st February 1840, a catastrophe occurred. The enormous embacle, that was created in Płonia, caused a blockade of waters outlet towards Gdańsk, which rose to impossible sizes and fell towards Baltic Sea, breaking Vistula Bar near Górki Wschodnie. In this way, the new arm and new Vistula mouth was created, named accurately by Wincenty Pol – Bold Vistula. As a result of this element in 1840, a peninsula was formed, which western part was the land of current Sobieszewska Island.

The man and his activity which contributed to the final formation of Sobieszewska Island, was to finally solve the problem of the flood on Żuławy. In order to create better conditions of Vistula waters and ices within 1889-1895, the channel was digged on a straight extension of Leniwka, 7,1 km long. This channel, called The Vistula Cross-Cut , was built between Świbno and Mikoszewo. It was solemnly opened on 31st of March 1895, at 3:45 p.m., on a personal order of the emperor Wilhelm II (Prussian annexation). In this way Vistula received a new, main mouth, whereas the western part of peninsula from 1840, became an insland in 1895, later named Sobieszewska.

Over 100 year old Sobieszewska Island is surrounded from the north by waters of Gdańsk Bay, from the east The Vistula Cross Cut, and from the west Bold Vistula. The island is an area of 32 km2, with 3,5 thousand residents. In relation to the size, it is the third biggest island of the Polish Baltic sea-short, giving way to Wolin and Uznam islands. However, Sobieszewska Island is the only one island in Poland, which was created as a result of human interference and that is why it deserves special attention.
