Tsarskiy Kurgan, Kerch, Crimea, 4th century BCE.
The structure features a unique corbelled system, where each successive layer of stone protrudes slightly inward to create a vault. This specific 36-meter-long entrance passage is called a dromos.
It is widely believed to have been the final resting place of a ruler of the Bosporan Kingdom, Leukon I.
