The Tower of Great Light(Hanbit Tower) is an observatory located in the Expo Science Park in Daejeon. The tower is a symbolic sculpture built to commemorate the Daejeon Expo held in 1993, and is called the Hanbit Tower because it is a ray of light that connects the present and the future. The 93-meter-high Hanbit Tower offers a bird's-eye view of the Expo Science Park and major areas of Daejeon. On the first floor, the Exhibition Room displays photos and audio-visual videos of major tourist attractions symbolizing Daejeon.
