An artificial ditch through Radunia river with dikes, associated buildings and greenery along the entire length of the object - from the lock to the west of Pruszcz Gdański up to the mouth of the canal to the Old Motlawa river in Gdansk.
The canal was laid out in 1338, and built in the years 1348 to 1356 by the Teutonic Knights. The idea of the implementation of this structure is commonly ascribed to the commander of the Gdansk and subsequently Grand Master of the Teutonic Order Winrich von Kniprode, but the real initiator of the construction was another commander of Gdansk (from the years 1333-1334), Jordan von Vehren.
The channel was intended primarily for the supply of fresh drinking water for Gdansk and the local castle of the Teutonic Knights, as well as a drive to Great Mill.
