Cheomseongdae (Korean: 첨성대; Hanja: 瞻星臺; lit. star-gazing tower) is an astronomical observatory in Gyeongju, South Korea. Cheomseongdae is the oldest surviving astronomical observatory in Asia,[1][2][3] and possibly even the world.[4][5][6] It was constructed during the Silla period, during the reign of Queen Seondeok (r. 632–647 AD).[7] Cheomseongdae was designated as the country's 31st national treasure on December 20, 1962.[8] It is part of Gyeongju Historic Areas, a UNESCO World Heritage Site.[9]
