Only one of many museums in Seoul, Leeum Museum of Art undoubtedly houses one of the city's most impressive art collections. Stunning architecture houses a seamless blend of traditional Korean treasures and thought-provoking contemporary works. The experience is beautifully curated, allowing you to journey from ancient ceramics to modern installations in a single visit. Don't miss the iconic spiral staircase, a photo opportunity in itself, and be sure to check their schedule for world-class special exhibitions, which are well worth the modest ticket price. Otherwise, the main gallery is free!
