Museum 209 is a small art museum that holds exhibitions on the third floor of a building near Jamsil Station and Lotte World Mall. It shows works made with light and shadow, like those of Vincent Bal, alongside video materials, photo zones, and interactive elements. The exhibition route is organized by theme and takes about 40 minutes to an hour to view. Signage at the building entrance is limited and the exhibition space is at the end of a corridor, making it hard to find.
