Marvel at the history and design of Cheomseongdae Observatory, the oldest surviving observatory in the world. Thought to have been built during the reign of Queen Seondeok in the 7th century CE, the structure consists of 362 pieces of granite, arranged in a bottle-like cylindrical shape that stands at 9.4 m (30.8 ft) tall and 5.7 m (18.7 ft) wide. The remarkable structure would have been useful in terms of agricultural production, because it allows for astronomical observation of seasonal change, while astrological myths and legends were closely linked with political power and spirituality.

  • I love the park around the observatory. An awesome area with a forest, a traditional pavilion, a hanok village. You can go at the peak of some hills and enjoy the beautiful view.
  • Moderately interesting as a handsome stone tower and reputedly the oldest star observatory in Asia, although how it functioned as such is not clear. Little shade and music via loudspeakers do not help.
