Chil Zena ("Forty steps"), also Chilzina or Chehel Zina, is a mountainous outcrop at the western limit of the city of Kandahar. Forty stone steps lead to the top of the outcrop, hence its name. It gives a commanding view on the city of Kandahar.[1] Chil Zena was located on the northern side of the old citadel of Old Kandahar, destroyed by Nadir Shah Afshar of Persia in 1738.[2] The carving of the staircase was commissioned by the Emperor Babur.[3] Chil Zena later received numerous inscriptions about the conquests of Babur (1526-1530), apparently carved by his son Humayun.
