A stone astronomical observatory in Gyeongju, South Korea, Cheomseongdae is considered the earliest significant archeological site in Korea dating back to the 7th century before the Unified Shilla dynasty. Considered the oldest existing observatory in East Asia, Cheomseongdae (Nearer the Stars Palace) is a familiar symbol on Korean coins and in travel literature, often symbolizing Korea itself. On December 20 1962, the Korean government designated Cheomseongdae their 31st national treasure

Structure Described

According to Samguk Yusa, Cheomseongdae was constructed under the reign of Queen Seondeok (632-647) near the capital of the kingdom. Cheomseongdae means "star gazing platform". The tower is built out of 362 pieces of cut granite which some claim represent the 362 days of the moon|lunar year. Some surveys of the site have indicated that there are 366 blocks. It has 27 circular layers of stones (some associate it with the fact that Queen Seondeok was considered to be the 27th ruler of Silla) surmounted by a square structure. 12 of the layers are below the window level and 12 are above. There are 12 large base stones set in a square, with three stones on each side. These sets of 12 may symbolize the months of the year.

The tower is 5.7 meters wide at the base and 9.4 meters tall, and filled with earth up to the level of the window. Its construction style parallels that used at the Bunhwangsa Temple in Gyeongju.

The Cheomseongdae is one of the oldest surviving observatories in East Asia, though some claim that Cheomseongdae was not suitable for astronomical observation. Others posit that it was used for astrology rather than astronomy, though during that era there was little differentiation between the two. Some scholars have argued that the Cheomsongdae's design was heavily influenced by Buddhism, noting similarities between its design and Mount Sumeru, the center of the world according to Buddhist mythology.
