Green rock of Hattusa a mystery

A giant ancient green rock located in the capital of the Hittite Empire in central Turkey is a centuries-old mystery. Visitors to Hattusa, the capital of the empire which lies near modern Boğazkale in Çorum province, admire the beauty of the rock.

Called a "wish stone" by locals, the rock's purpose has yet to be revealed. The rock is different from all others found at the site and is serpentine or nephrite. Researchers believe the stone was used by all civilizations after the Hittites.

The Hittite Empire in the Late Bronze Age was one of the civilizations that played an important role.
