Beautiful and definitely worth seeing if you are already visiting COEX or Gangnam. The huge bookshelves and open space are genuinely impressive in person, and entrance is completely free. 📚✨However, I wouldn’t come across Seoul just for the library. It gets very crowded, with many visitors mainly taking photos, so it doesn’t really feel like a quiet traditional library. Finding a seat can also be difficult during busy hours.Still, it’s a unique place to walk around, take photos, browse some books or magazines, have a coffee, or simply take a break while shopping. I especially liked that it feels like a public cultural space rather than just another attraction inside a mall. Worth a stop, but keep your expectations realistic!
