Jōkyū War
In feudal Japan, the Jingi-kan became the final surviving building of the Heian Palace. During the Jōkyū War in 1221, most of the palace was evacuated and fell into disrepair; the Jingi-kan alone remained in operation. A 1624 memoir by a "Jingi-haku" reports that the Jingi-kan was still being used as late as 1585 and was demolished during renovations. In 1626, a temporary building was constructed to perform additional ceremonies.
