Gwanghwamun Gate (광화문)

From Korea’s Tourism website: Founded in 1395 by the first king of the Joseon Dynasty, Gwanghwamun is the main gate of Gyeongbukgung Palace. Literally translated, its name means “may the light of enlightenment blanket the world”, and implies the resounding dedication the people of the Joseon Dynasty had in creating a new dynasty. Constructed solely out of granite, its center is an entrance that resembles a rainbow, called Hongyemun. Above that is a gate tower.
