A large business hub, Samseongdong is anchored by Korea’s World Trade Center, where many important business exhibitions and meetings are held. The enormous COEX mall sprawls underground, providing a myriad of things to do and see, including a large aquarium and movie theater. For a bit of peace and zen, head over to the ornate Bongeunsa Temple which is one of Korea’s most important places of worship. Or take a stroll nearby through the tranquil royal burial grounds of Seonjeongneung, a UNESCO World Heritage Site.
