Chełmno

Chełmno ([ˈxɛu̯mnɔ] ; older English: Culm; German: , formerly also Culm) is a town in northern Poland near the Vistula river with 18,915 inhabitants as of December 2021. It is the seat of the Chełmno County in the Kuyavian-Pomeranian Voivodeship.
Due to its regional importance in the Middle Ages, the town gave its name to the entire area, Chełmno Land (and later an administrative unit of the Kingdom of Poland, the Chełmno Voivodeship), the local Catholic diocese and Kulm law, a municipal form of government for cities and towns around Poland, including the current capital city of Warsaw.
