Seokbinggo (Korean stone icehouse)

A Joseon ice store at Wolseong

Seokbinggo means a stone ice store. Gyeongju’s surviving example stands along the northern side of the Wolseong fortress area, with its long axis running north to south. It held ice, rather than fermenting food or serving as an ordinary household cellar. The present monument belongs to the Joseon period.

An inscription on the stone stele and the entrance lintel records that Jo Myeong-gyeom rebuilt an earlier wooden ice store in stone in 1738. The inscription also records its relocation from a site to the west four years later. These dates describe the surviving Gyeongju building; they do not establish when Koreans first stored ice or when every seokbinggo type began.

A descending entrance and arched stone chamber

The entrance is on the south side. Stairs descend from it into a long chamber partly set below ground. The roof forms a stone arch, and three openings connect its upper part with the outside air. Inside, the floor falls toward a drain so meltwater can run out. These visible features belong to this particular Gyeongju store and should not be treated as a plan for every Korean icehouse.

A 2022 study gives the chamber dimensions as 19.86 metres long, 5.94 metres wide and 4.97 metres from floor to the arched ceiling. Those measurements describe this monument, not a standard size. The photograph linked here shows its interior masonry and arch; it does not show ice, the exterior roof or an operating storage season.

The generated cutaway illustrates the documented relationship between the chamber and ground, entrance, roof openings and drainage. It is explanatory editorial art, not a measured construction plan or a reconstruction of the building's present excavated state.

Heritage building and present-day measurements

The building is now a protected heritage site, not an active ice store. Researchers measured temperature and relative humidity at five interior points between October 2019 and October 2020 and sampled soil for a separate microbial dataset. Those modern readings document the environment of the monument and its conservation concerns; they are not measurements of an eighteenth-century ice-storage season or a food-safety process.

Gyeongju Seokbinggo and the Iranian yakhchāl are related by the broad task of holding winter ice for later use, but their regional histories and building forms differ. The link to the yakhchāl is a comparison of that storage function, not a claim that the structures share a design or cultural origin.
