Set around the Tamgaly Gorge, amidst the vast Chu-Ili mountains, is a remarkable concentration of some 5,000 petroglyphs (rock carvings) dating from the second half of the second millennium BC to the beginning of the 20th century. Distributed among 48 complexes with associated settlements and burial grounds, they are testimonies to the husbandry, social organization and rituals of pastoral peoples.
