The six-century old town: two royal palaces, the Confucian ancestral shrine, a hillside of 1930s hanok, and a 1905 market — all within about twenty minutes' walk of each other, with Bugaksan and Inwangsan rising directly behind. Ceremonial and orderly by day around Gwanghwamun; scruffy, loud and cheap by night around Jongno 3-ga.
Who it's for: First-time Seoul visitors — this is the one district you cannot skip. History, architecture and palace people. Walkers, since almost everything here is on foot. Anyone who wants both the most refined and the cheapest eating in the city within a few blocks.
