Korea's and Iran's long-running relationship started with cultural exchanges date back to the Three Kingdoms of Korea era, more than 1600 years ago by the way of the Silk Road. A dark blue glass was found in the Cheonmachong Tomb, one of Silla's royal tombs unearthed in Gyeongju. An exotic golden sword was found in Gyerim-ro, a street also located in Gyeongju. These are all relics that are presumed to be sent to Silla from ancient Iran or Persia through the Silk Road. Other items uncovered during the excavation include a silver bowl engraved with an image of the Persian goddess Anahita; a golden dagger from Persia; clay busts; and figurines portraying Middle Eastern merchants.
