Namhansanseong Seomun Observatory
Perched on the ramparts of a UNESCO-listed mountain fortress just southeast of Seoul, the Namhansanseong Seomun Observatory is one of the capital region's most celebrated viewpoints. From the platform beside the West Gate, a vast panorama stretches across the city—Lotte World Tower, N Seoul Tower, the Han River, and ridgelines fading into the distance. Locals flock here at sunset and after dark to watch the skyline transform from molten gold to a glittering sea of lights.
