Located in the middle of the wealthy Gangnam district of Seoul, COEX Mall is Asia’s largest underground shopping center. Within the large mall is a beautiful book paradise, Starfield Library, which is open to the public free of charge. The impressive two-story library has a magnificent glass ceiling that lets natural light shine on the towering shelves of books. Last Christmas, an installation, the“ Starfield Book Tree,” grabbed the attention of book lovers. It was made up of over 14,000 books that were piled together to create an image of happy animal families sledding down a hill. This is a place that every bookworm would love to spend a whole day in.
