The Leeum is one of the most excellent art museums in the world with eclectic architecture and a collection of art that pushes the imagination in new directions. They have an excellent Korean collection that shows off excellent pieces of pottery, sculpture, and paintings. A walk through their Korean collections gives an insight to the Korean collective.
Their modern western collection is also top notch with pieces from Andy Warhol, Willem de Kooning, Mark Rothk, and Yoshimoto Nara. There is also the breathtaking spider sculpture outside called Maman by Louise Bourgeois.
