Preservation work has begun on the ancient Armenian stone statues on Mount Nemrut, a UNESCO World Heritage site in present-day Turkey; restoration efforts started in 2022 and have shown positive results, with nano solutions like nano limestone being used to enhance the longevity of the symbolic monuments, led by the Gaziantep Regional Restoration and Conservation Laboratory and the Adıyaman Museum Directorate; the Armenian Pantheon of Gods on Mount Nemrut was erected in 63 BC by King Antiochus I Theos of the Orontid (Yervanduni) Dynasty of the Armenian Kingdom of Kamakh (Commagene), whose great-great grandfather was Armenian King Orontes IV; Antiochus combined Parthian and Armenian traditions to reinvigorate his ancestral religion, creating seated statues with inscribed names that were later decapitated, their heads now scattered across the site.
