This I visited the ancient tomb of Darius the Great in Iran—and it left me speechless.This hidden valley, carved into a cliffside near Persepolis, holds the final resting places of Persian kings who once ruled one of the largest empires in history. Standing before the tomb of Darius I, I couldn’t help but think about how this man changed the course of the ancient world—from building roads and uniting cultures, to shaping systems we still use today. #i̇ran #persia #persian #irantravel #petra | Th
