The statue is symbolically pointed east towards his birthplace. It is on top of the Genghis Khan Statue Complex (a tourist centre),10 metres (33 ft) tall, with 36 columns representing the 36 Khans from Genghis to Ligdan Khan. It was designed by sculptor D. Erdenebileg and architect J. Enkhjargal and erected in 2008.

Visitors climb up to the head of the horse through its chest and neck, where they can have a panoramic view. The main statue area is surrounded by 200 yurts (tents), designed and arranged like the pattern of the horse brand marks that were used by the 13th-century Mongol tribes. The cost of the complex is reported to be US$4.1 million, spent by The Genco Tour Bureau, a Mongolian company.
