Ganjnameh (Persian: گنجنامه, romanized: Ganjnāme, lit. 'Treasure Book') is located 12 km southwest of Hamadan (ancient Ecbatana) in western Iran, at an altitude of c. 2000 meters across Mount Alvand. The site is home to two trilingual Achaemenid royal inscriptions. The inscription on the upper left was created on the order of Achaemenid King Darius the Great (r. 522–486 BC) and the one on the right by his son King Xerxes the Great (r. 486–465 BC).
