After the battle, the King of Poland, Władysław II Jagiełło, intended to erect a chapel on the battlefield at "loco conflictus nostri ... dicto Grunenvelt".
Despite the Polish–Lithuanian victory in the battle and the war, the battle site remained under the control of the Teutonic Order until 1525, although since 1466 under Polish suzerainty as a fief, and they built a chapel dedicated to Mary instead.

After the defeat of Nazi Germany in World War II, in accordance to the Potsdam Agreement, the village became part of Poland.
A museum and memorial site are located in the fields where the battle was fought, roughly in the middle of a triangle, with Stębark and Łodwigowo.
