N Seoul Tower was built in 1969 as Korea's first integrated transmission tower beaming television and radio broadcasts across the capital. Since opening to the public in 1980, it has become a much-loved Seoul landmark. The tower's main attractions include multi-colored digital art projected onto the tower at night, a digital observatory, a roof terrace, the HanCook restaurant, the n.Grill restaurant, and the Haneul (Sky) Restroom. N Seoul Tower's mountain surroundings on Namsan (Mt.) have made it a popular place to unwind for locals and tourists alike.
