Iwakuni's chief claim to fame is this graceful bridge, built in 1673 during the rule of feudal lord Kikkawa Hiroyoshi. It has been restored several times since then, but its high arches remain an impressive sight over the wide river, with Iwakuni-jō atop the green hills behind.
In the feudal era, only members of the ruling class were allowed to use the bridge, which linked the samurai quarters on the west bank of Nishiki-gawa with the rest of the town. Today, anyone can cross over for a small fee.
