The village was first mentioned in 1570. Kuźnica was a royal village of the Polish Crown, administratively located in the Puck County in the Pomeranian Voivodeship. In 1635, in the face of a Polish–Swedish War, Polish King Władysław IV Vasa ordered the construction of the Kazimierzowo sea fort. During the Swedish invasion of Poland ("Deluge") in 1655 the Poles withdrew to Puck, and Kazimierzowo was taken over by the Swedes. After the war Kuźnica developed as a fishing village.
