N Seoul Tower really comes alive at night with a breathtaking array of light shows from the "Reeds of Light" whose 70 lights create dynamic displays changing with every gust of wind, to the "Shower of Light" where light seems to cascade from a shower head for three minutes when a 100 won coin is inserted. Both shows can be enjoyed without an admission fee. More lights are created from the transmission tower, observation platform, main tower and the tower plaza, constantly changing their colors and patterns with the season and weather, making N Seoul Tower a true nighttime spectacle.
