Near the center of the Peace Memorial Park in Hiroshima, Japan is a concrete, saddle-shaped monument that covers a cenotaph holding the names of all of the people killed by the bomb. The monument is aligned to frame the Peace Flame and the A-Bomb Dome. The Memorial Cenotaph was one of the first memorial monuments built on open field on August 6, 1952. The arch shape represents a shelter for the souls of the victims.
Simple but powerful.
