In Onomich, visiting various old temples is one of the pleasures for tourists.
Among them, Senko-ji is one of the main places of pilgrimage to famous old temples, and most visitors to Onomichi come here. The temple is said to have been founded in 806.
The vermillion-lacquered main hall is also called the Red Hall and, together with the bell tower famous for chimes on New Year's Eve, is a symbol of Onomichi. The big rock beside the main hall, Tama no Iwa, is said to have been a landmark for voyages due to a shining gem placed on it in the past.
