A city rich in history and culture, Incheon attracts people of all kinds. During the Korean War, Incheon was a critical region because the Han River crossing in Seoul could be accessed from waters off the coast of Incheon. The Incheon Landing Operation Memorial Hall is dedicated to the Incheon Landing in the Korean War. Incheon also has Korea’s official Chinatown, so many people visit to taste the original jajangmyeon first developed by Chinese immigrants. Also, the new city of Songdo in Incheon is a popular filming site among advertisers who want to showcase their products as futuristic and new.
