Ages ago a wind-ship swam to Gdańsk. Near Rozewie a huge storm broke out and the crew seeing there was no other hope, offered themselves to Our Lady with baby Jesus, whose statuette of was on the ship. Their prayers were heard. Exhausted sailors with rest of their strengths have pulled the figurine out of the sea. In gratitude, they decided to leave it by the countryside's well. In the half of XVth century fishermen of Swarzewo moved the statue to the St. Peter and Paul's Church on Hel. In 1525 in the reformation times, luterans, wanting to fight the cult of Saint Mary, plumbed the statuette into the sea. It took not even a day for it to swim back to Swarzewo again,almost like it would always want to remain in this place.
The statuette has survived all the wars, conflicts and acts of thievery. Since Poland's Wedding to the Sea many polish figures have prayed to it for good fortune over the years. One of the worth mentioning is General Joseph Haller
