Hiroshima, a modern city on Japan’s Honshu Island, was largely destroyed by an atomic bomb during World War II. Today, Hiroshima Peace Memorial Park commemorates the 1945 event; on-site is Genbaku Dome, the surviving portion of a structure that crumbled in the explosion. Other prominent sites include Shukkei-en, a formal Chinese-style garden, and Hiroshima castle, a fortress surrounded by a moat and a park.
