Gyeongju Expo Grand Park is a large park that holds Gyeongju Tower and several exhibition halls together. It contains the 82-meter-high observation deck of Gyeongju Tower, the Solgeo Art Museum, the Natural History Museum, and the light art piece Cheonma's Palace. The parking lot is large, and a walking path connects the exhibition halls, with free admission during events. Because the park is large, seeing all of it takes considerable time.
