The existence of the town was first documented in 1124. In 1249 Gartz was granted town privileges by DukeBarnim I of Pomerania. Because of its strategic location on the river, the town was frequently vulnerable during military campaigns.
Since the Oder-Neisse line was made the German-Polish border in 1945, Gartz is now a border town.
