A glowing laser-and-art spectacle on Nodeul Island has drawn nearly 300,000 visitors in its first week alone, turning an island in the middle of Seoul’s Han River into one of Asia’s most captivating nighttime destinations this autumn. The Seoul Metropolitan Government said Thursday that about 299,000 people attended from the opening through Monday, as families, couples and international visitors gathered for light installations along the Han River.
