Seoul’s long-awaited new arts-and-leisure center has made waves—literally—since its construction in 2011, and grand opening in 2014. That’s because the architectural jewel known as Soem Sevit, a trio of striking glass edifices built on artificial islets, is helping to set in motion a waterfront rejuvenation in this hyper-urbanized capital city. (The islets, tethered by walkway to the southern bank of the Han River, can be seen in the 2015 Hollywood action film Avengers: Age of Ultron.) Soem Sevit, translated as “Three Shining Islands,” consists of curved modern structures named Gevit, Chavit, and Solvit, which house state-of-the-art exhibition halls, art galleries, performance spaces, and a range of both high-end and casual restaurants; a fourth floating structure, called Yevit, is an amphitheater with a stage and jumbo LED screen for outdoor movie screenings and concerts. Soem Sevit is accessible by foot from Banpo Hangang Park, which lies at the foot of Banpo Bridge and its famous rainbow fountain.
