At Chilbulsa's Ajabang on Jirisan, what became national heritage was not the room but the ondol beneath its floor

How we checked

Checked October 4, 2026. We compared the video against the original texts of the Cultural Heritage Administration's designation preview press release (October 6, 2023) and designation notice (December 22, 2023), the Korea Heritage Service's designation press release, the National Heritage Digital Service descriptions of the “Ajabang Ondol of Chilbulsa Temple, Hadong” (하동 칠불사 아자방 온돌) and of the former Gyeongsangnam-do Tangible Cultural Heritage “Ajabangji of Chilbulsa Temple, Hadong” (하동 칠불사 아자방지), the Hadong County press release (January 29, 2016), the Chilbulsa Temple website, and the Academy of Korean Studies' Digital Hadong Culture Encyclopedia (디지털하동문화대전). Three sentences about the early-1980s restoration (the floor thickness, the rushed work, and the “three days” of warmth) were confirmed only through Busan Ilbo reports, and the sentence saying fires are lit in the firebox again today only through Buddhist media reports (△). “Only the number of days had been handed down; no one knew the shape beneath the floor” does not appear as such in any source, so it is marked as interpretation.

• “100 days on one firing” is what Hadong County and Chilbulsa say; the Korea Heritage Service texts give no number of days for the warmth. The former Gyeongsangnam-do description says “a month.”
• The Korea Heritage Service's reasons for designation are the rarity of combining traditional ondol with a meditation hall and the meditation-hall function confirmed by Goryeo-period artifacts. “The gudeul survived intact beneath a building that burned twice” is a sentence from the Hadong County press release, which connects it to the 1976 designation as a Gyeongsangnam-do Tangible Cultural Heritage.
• The sources differ on the fire years (1800 or 1830; 1948, 1949, or 1951) and the restoration years (begun in 1978, 1982–83, or 1983), so the video gives no years.
• The excavation year is 2017 according to the Korea Heritage Service and 2016 according to Busan Ilbo, so the video says only “the excavations that followed.” We did not see the original excavation report.
• That the warmth fell to three days after the early-1980s restoration, and the 1-meter floor thickness, appear in only one report, and we did not find original measurement records.
• We do not give people's names or street addresses.
