As the name suggests, Cheomseongdae was a place used to watch the stars in ancient times. It was built in the period of Queen Wang Sundeok, the 27th generation of Silla. During the Silla period, it was mainly used as an astronomical observatory. The entire Cheomseong Tower is built of granite, with a height of 9.17m, a diameter of 3.1m at the upper end and a diameter of 5.17m at the lower part. The length of one side of the foundation stone base is 5.35m. The double-layer foundation stone base and the altar are square, and the size is 8 times and 15 times that of the long platform stone respectively. On the stone base is a 27-story cylindrical tower. The entire Zhanxing platform is wide and narrow at the bottom and stands upright. The height of each floor of Cheomseongdae is about 30cm, and the top is a double-layered stone altar. The top is a tic-tac-toe shape, and the connecting part is a barrel-shaped round body, because it is often mistakenly called "star picking platform".
