Most museums (including the National Museum of Korea) close on Mondays, and Changdeokgung Palace does too. Gyeongbokgung closes on Tuesdays instead. Markets, shopping streets and temples stay open daily.
Plan palaces around the split: Gyeongbokgung on Monday, Changdeokgung any day but Monday. If a public holiday falls on Monday, many museums close Tuesday instead.
