Cheomseongdae is the oldest astronomical observatory in East Asia. Cheomseongdae Observatory was built during the reign of Queen Seondeok (r. 632-647) of the Silla Dynasty, for observation of the movements of heavenly bodies.

Cheomseongda stands 9.17 meters high, 5.7 meters wide at the base, and 9.4 meters tall. Cylindrical in shape, it resembles the upper part of a milk bottle. It consists of three parts, a stylobate, or base upon which a column is constructed, a curved cylindrical body, and a square top. Midway up the body stands a square window and entrance to the inside of the structure.
