An exhibition on Seokguram Grotto, an eighth-century Buddhist cave temple among Korea's first UNESCO World Heritage sites, opened in Paris on Thursday (local time), alongside a weeklong Korean heritage festival, the Korea Heritage Service (KHS) said Friday. The exhibition, "The Millennium Mystery of Buddhist Art: Seokguram," runs through March 13, 2027, at the Korean Cultural Center in France. The KHS organized it with the center and the Gyeongju city government to mark the 140th anniversary of diplomatic relations between Korea and France. Seokguram is an artificial granite grotto on Mount Toham in Gyeongju, the capital of the Silla Kingdom (57 B.C.-A.D. 935). It was added to the UNESCO list in 1995. The show features a 3D immersive video recreating the grotto's interior and a reconstruction of green-glazed tiles depicting Buddhist guardian deities that once decorated a wooden pagoda base at the Sacheonwang Temple Site in Gyeongju. Korean Ambassador to France Kwon Hyuk-woon gave opening remarks, followed by congratulatory speeches from Rep. Kim Seok-ki, Gyeongju Mayor Joo Nak-young and
