Yeon-deung-hoe — the Lotus Lantern Festival — is Seoul’s most visually spectacular spring heritage event, celebrating Buddha’s Birthday with the famous Lotus Lantern Parade down Jongno (May 16–17, 2026). Listed as a UNESCO Intangible Cultural Heritage since 2020, the festival brings tens of thousands of participants carrying hand-made lotus lanterns from Dongdaemun to Jogyesa Temple in a slow, luminous procession that fills the entire street. The two-week buildup sees Jongno and Insadong hung with thousands of hanging lanterns, transforming the neighborhood into one of the most beautiful night scenes in Korea.
Saturday evening (May 16) is the main parade — the full street procession from Dongdaemun to Jogyesa Temple. Sunday (May 17) hosts the Eoulim Madang traditional folk performance festival in the Jogyesa courtyard. Both days are free to attend. The parade is one of those rare city events where the spectacle entirely justifies the crowds — lantern light at scale has a warmth and softness that photos cannot fully capture.
