Rainy-day Seoul: an indoor culture route

Start around Gwanghwamun or City Hall so you can move between indoor stops without losing the day to weather. Choose one museum, one bookstore or design shop, and one calm cafe rather than trying to cross the whole city. Keep a T-money card ready, use subway-connected exits when rain is heavy, and save palace courtyards or river walks for the evening if the sky clears. This route works best for first-time visitors who want culture without a complicated itinerary.
