Introduction
Gyeongju Cheomseongdae is an ancient astronomical observatory located in Gyeongju, South Korea. It is considered to be one of the oldest observatories in East Asia and has become a popular tourist attraction due to its unique historical and cultural significance. In this post, we will explore the history, architecture, function, and preservation efforts of Gyeongju Cheomseongdae.
Historical Background
Gyeongju Cheomseongdae was built during the reign of Queen Seondeok (632-647 AD), the first queen of the Silla Kingdom, which was one of the Three Kingdoms of Korea. The exact purpose of the observatory is not known, but it is believed to have been used for observing celestial bodies and making astrological predictions. It is also speculated that it was used for conducting rituals related to astronomy and astrology.
The Silla Kingdom was known for its advanced culture and technology, and Gyeongju was its capital. Gyeongju Cheomseongdae was built in the center of the city and was likely used by the royal court as well as scholars and astronomers. The observatory was abandoned after the fall of the Silla Kingdom in 935 AD and was later rediscovered during the Japanese occupation of Korea in the early 20th century.
Today, Gyeongju Cheomseongdae stands as a testament to the advanced astronomical knowledge and sophisticated technology of the Silla Kingdom. It has been designated as a National Treasure of South Korea and is a popular destination for both tourists and locals alike.
Architecture and Design
Gyeongju Cheomseongdae is a cylindrical tower made of 362 granite stones, each measuring about 30 cm in length and 50 cm in width. The tower stands at a height of 9.17 meters and has a diameter of 5.7 meters at the base, tapering to 4.8 meters at the top.
The design of the observatory is simple yet sophisticated. The stones used in the construction were carefully cut and fitted together without the use of mortar or any other binding material. The base of the tower is made up of 12 large stones arranged in a circle, while the top is capped with a single stone slab. The tower also has 27 square-shaped holes, arranged in four horizontal rows, that serve as observation points.
The number of stones used in the construction of Gyeongju Cheomseongdae is significant, as it is believed to have been constructed based on the ancient Korean system of numerology, which considered odd numbers to be auspicious. The tower's shape, with its circular base and tapering cylindrical form, is also significant, as it was believed to represent the shape of the universe.
Overall, Gyeongju Cheomseongdae's unique design and sophisticated construction demonstrate the advanced architectural and engineering skills of the Silla Kingdom. It is considered to be a masterpiece of ancient Korean architecture and continues to inspire admiration and awe in visitors to this day.
Significance and Function
Gyeongju Cheomseongdae's significance lies in its function as an astronomical observatory and its representation of the advanced astronomical knowledge of the Silla Kingdom. The tower is believed to have been used for observing celestial bodies and making astrological predictions. The 27 observation holes on the tower correspond to the 27 constellations of the lunar-solar calendar, which was used by the Silla Kingdom.
The tower's design and construction also hold significant symbolic meaning. The circular base of the tower represents the earth, while the tapering cylindrical form represents the heavens. The observation holes were used to mark the position of the sun and the stars, and it is believed that the tower was used to measure the length of daylight hours and the time of the year.
Gyeongju Cheomseongdae's astronomical observations were used for various purposes, including determining the timing of important ceremonies and events, and for agricultural purposes such as predicting the start of the planting season. The observatory was also used for astrological purposes, such as predicting the fortunes of the royal family and the nation.

Restoration and Preservation Efforts
Gyeongju Cheomseongdae has undergone several restoration and preservation efforts over the years to ensure its longevity and to protect it from natural disasters and other threats.
In 1966, the Korean government carried out a major restoration project to reinforce the tower's structure and prevent further deterioration. During the restoration process, the original stones were removed and numbered before being put back together to ensure their proper placement. The project also involved the addition of a protective layer of concrete around the base of the tower to prevent water damage.
In 2012, a second restoration project was carried out to repair cracks and reinforce the observatory's structure. This restoration included the use of traditional Korean techniques, such as the use of Korean paper and a mixture of soil and lime for mortar, to ensure the authenticity of the tower's construction.
In addition to restoration efforts, Gyeongju Cheomseongdae is also protected by the Korean government as a National Treasure. The observatory is regularly inspected and monitored to ensure its safety and to prevent damage from natural disasters and other threats.
Overall, the restoration and preservation efforts for Gyeongju Cheomseongdae demonstrate the importance of protecting and preserving the cultural heritage of South Korea and the world, and ensuring that future generations can continue to appreciate and learn from this ancient astronomical observatory.
