Itsukushima Shrine - Miyajima Island in the inland sea was once thought to be so sacred that human beings were not permitted to live on it. Itsukushima Shrine was constructed over water so that humans would not "pollute" the sacred island. Today many ferries carry traffic between the island and Hiroshima. Because the island is still sacred, trees may not be cut for lumber. Deer roam freely as they are thought to be sacred in the Shinto religion as messengers of the gods.
