GYEONGJU, North Gyeongsang Province — Cheomseongdae Observatory, one of Asia’s oldest surviving astronomical observatories and a symbol of Silla-era astronomy, has been transformed into a nighttime spectacle ahead of the 2025 APEC summit.
On Monday, the Korea Heritage Service and the city of Gyeongju launched a special projection mapping show titled “Time of the Stars” at the observatory’s exterior. The media facade will be presented nightly through Nov. 1, coinciding with the APEC summit. The organizers are considering making the show a permanent feature depending on public feedback.
The 7-minute show uses advanced projection technology to turn the entire surface of Cheomseongdae into a canvas. The show begins with a Silla-era (57 BC-AD 935) astronomer climbing the tower to observe the stars, followed by sweeping visuals of the Milky Way, meteor showers and comets.
It also features elements of Korea’s astronomical legacy, including the Celestial Chart from the Joseon Kingdom (1392-1910), which contains 1,467 stars and the 28 traditional East Asian constellations. The four guardian deities of the cardinal directions — the Blue Dragon, White Tiger, Vermilion Bird and Black Tortoise — appear in turn, blending myth and science in a dynamic display.
The projection is open to all visitors and aims to reimagine Cheomseongdae not just as a historic monument, but as a living stage where light and storytelling come together. Organizers hope it will become a beloved nighttime tourism attraction for both Koreans and international visitors.
