KRO meaning in Airport Code ?

A kurgan (Russian: курга́н, Ukrainian: курга́н, висока могила) is a type of tumulus constructed over a grave, often characterized by containing a single human body along with grave vessels, weapons and horses. Originally in use on the Pontic–Caspian steppe, kurgans spread into much of Central Asia and Eastern, Southeast, Western and Northern Europe during the 3rd millennium BC.

The earliest kurgans date to the 4th century BC in the Caucasus, and researchers associate these with the Indo-Europeans. Kurgans were built in the Eneolithic, Bronze, Iron, Antiquity and Middle Ages, with ancient traditions still active in Southern Siberia and Central Asia.
