In Red Cavalry, Isaac Babel includes a one-page description of the Jewish cemetery in Kozyn. 'A cemetery in a Jewish shtetl. Assyria and the mysterious decay of the East on the weed-cluttered fields of Volyn.'[2]
Until 26 January 2024, Kozyn was designated urban-type settlement. On this day, a new law entered into force which abolished this status, and Kozyn became a rural settlement.[3]
