Hyehwa is Seoul's small-theatre district, a lively area around Daehangno where performance spaces, cafes, and late-night street life cluster north of the old palace districts. It is not a single monument, but it is one of the better places in central Seoul to feel the city's independent stage culture.
Come in the evening, when the theatres are busiest and the surrounding streets fill with students, actors, and small crowds choosing a show or a cafe.
