The Shrine was transfered to the present location in 972(tenroku 3). The main temple and the oratory are the important cultural properties of the country, and are famous for the greatest size in Japan.
Hiromine Shrine deifies Susano-no-Mikoto as main God, and that is said to trace back to ritual of Shin-ko Empress in ancient times. A branch was founded at Katsuhara in Ymanashiro in 869(Jogan 11). That is the reason why Hiromine Shrine is called “Gion-Honja Harima-Koku Hiromine-Sha”. Hiromine Shrine became to be considered as a branch of Gion-Yasaka Shrine, because Gion-Yasaka Shrine developed greatly. But Hiromine was a headquarters essentially.
