"Spectators from across the country and abroad gathered along Seoul's Hangang River on Saturday for the 2025 Hangang Bitseom Festival, Korea's largest waterfront laser art event. Footage shows powerful beams of light sweeping across the night sky, transforming the riverside into a vast open-air gallery. Visitors explore vibrant light tunnels, laser fountains, and illuminated bridges that paint Seoul's skyline in colour. "It's really beautiful, especially in the rain, when the light hits the water. I love it. It's beautiful," shared a spectator. "It's immersive, and I like how they use different types of, I guess, elements, like that one sound. They have water over there," remarked another. He added, "It's a great way to impact people, and bring young and old people together, to teach them new things and show them how creative people can get." The festival, organised by the Seoul Metropolitan Government, takes place annually across six islands along the Han River, offering visitors a unique experience where nature, art, and technology come together. Running from October 2 to 12 under the theme 'Spectra of Light', this year's event features seven large-scale laser installations exploring the fusion of art, technology, and the natural landscape. Beyond the exhibits, more than 3,000 participants took part in the 'Light Run', a five-kilometre night race where runners wearing LED lights formed a glowing ribbon along the river. Now in its third year, the Hangang Bitseom Festival has become a highlight of Seoul's cultural calendar, attracting residents and tourists alike to celebrate the city's growing reputation for digital and public art."
