POSCO Center

Posco Center is an office building in Gangnam-gu, Seoul, between Samseong Station and Seolleung Station, with a Terra Rosa coffee shop, a food court, and a bookstore. It also holds a basement art museum, a cylindrical aquarium, and a cafe on the first floor. In the free aquarium, sharks are visible along with a Nam June Paik sculpture and crashed spacecraft debris. Because it is a working office space, visitors cannot enter areas outside the designated zones.
