The first written mention of Łabiszyn comes from the 13th century as an estate owned by a knight, located within medieval Piast-ruled Poland. A document from 1247 mentions Dezydery of Łabiszyn, probably the owner of the settlement. In 1362 the village is mentioned as "Labissino" and "Lambissiono." In the 14th century, Łabiszyn belonged to the Prawdzic family. Thanks to their efforts, the settlement and the castle were granted town rights in 1369. In 1407, the town already had its own wax seal with the coat of arms depicting the right, open and severed hand with the inscription "Łabiszyn". King Władysław Jagiełło passed through Łabiszyn on November 2, 1410 , on his way from Inowrocław to Szubin after the victorious Battle of Koronowo. According to tradition, Jagiełło planted two oaks on the Łabiszyński Hill, one of which has survived to this day.
