Cheomseongdae is an astronomical observatory from the Silla period, built during the 7th century in the former capital of Gyeongju, where it still stands today. It is one of the oldest surviving observatories in the world, and Korean tourism promoters usually claim it to be the oldest in Asia, though it is disputed whether it was indeed suitable for astronomy or if it was meant instead to be symbolic of Silla's achievements in science. It was designated National Treasure number 31 on December 20, 1962.
[edit] Construction
Built sometime during the reign of Queen Seondeok, Cheongseomdae was constructed of granite and its features suggest a high degree of symbolism; the exact number of pieces used is disputed -- estimates range from 362 to 366, as a 1962 survey found -- but regardless, they are believed to symbolize the number of days in a year and are arranged in 27 layers which may be a celebration of Queen Seondeok having been Silla's 27th ruler. Perhaps symbolizing the 12 months of the year, there are 12 layers below the window, 12 above it, and 12 make the base as well. The stones at the very top are arranged into a shape similar to the hanja character 井; the shape is visible from the 19th to 20th and 25th to 26th steps, perhaps suggesting that ladders were meant to be placed there by the person making astronomical observations. The window faces southeast.
The method of the tower's construction has been compared to that at Bunhwangsa, also in Gyeongju, and is likewise believed to have come from Tang Dynasty China with which Silla was allied.
The tower stands 9.4 meters and is 5.7 meters at its base. On the inside, dirt has been packed in up to the window, presumably for an astronomer to stand on. Other than the fact that it now tilts a bit to the northeast, it is today as it always has been.
