Seoul Light DDP
Seoul Light DDP projects a large-scale media-art show onto the Dongdaemun Design Plaza's 222-meter curved facade. Based on the city's published winter schedule, the 2026 winter edition is expected to run December 17–31, 2026, with screenings roughly every half hour from 18:00 to 22:00. A New Year's Eve countdown program is typically added on December 31 in the last hour before midnight. This is separate from the shorter "Seoul Light DDP Fall" edition, which already ran in September 2026.
Getting there: Dongdaemun History & Culture Park Station (Lines 2, 4 and 5) connects directly to the DDP building through underground exits — you don't need to surface far from the venue.
Seoul Light Gwanghwamun
Seoul Light Gwanghwamun is a separate media-art festival staged around Gwanghwamun Square, typically featuring a media-facade exhibition, light sculptures, and installations from a mix of Korean and international artists. Recent editions have run roughly from mid-December through early January, with operating hours generally in the range of 17:30–21:30 on weeknights and slightly later on weekends. The 2026–27 edition's exact dates were not yet finalized as of this review — check the festival's own site (linked below) or Seoul's cultural event calendar closer to December.
Getting there: Gwanghwamun Station (Line 5), Exit 2, or Gyeongbokgung Station (Line 3), Exit 5, both a short walk from the square.
Seeing both in one night
DDP and Gwanghwamun are roughly 15–20 minutes apart by subway (via Line 5, changing isn't usually required depending on your route), so seeing both in one evening is realistic if you plan the order. A practical sequence: start at Gwanghwamun in the early evening when the square is calmer, walk or take a short subway ride toward Euljiro to see the Seoul Lantern Festival displays along Cheonggyecheon Stream if it's running that week, then finish at DDP for its later evening screenings. Expect all three areas to be significantly more crowded on Friday and Saturday nights and around the New Year's Eve countdown.
Photo tips
At DDP, the widest unobstructed view of the curved facade is from the plaza directly in front of the building rather than from the side ramps. At Gwanghwamun, arriving in the 30 minutes right after sunset (rather than after full dark) usually gives a more balanced photo with some ambient light still in the sky behind the illuminated square. Bring a phone or camera that handles low light reasonably well — flash won't reach the facade-scale displays at either venue.
