On August 9, 1945, the US Army Air Force dropped the plutonium-fueled Fat Man atomic bomb over Nagasaki, Japan, in the second, and so far the last, atomic bombing of a population. The Manhattan Project facility at Hanford produced the plutonium used in the Fat Man bomb and in the Trinity Test on July 16, 1945.    

Each year on August 9, the park hosts Lights for Peace in Richland that features music from the Mid-Columbia Mastersingers, a guest speaker, and an opportunity to ring a peace bell. Staff also display luminarias with messages of peace from the public along a path that the public is encouraged to walk for a quiet, contemplative experience.  

Commemorative Events

Every July, we post a full schedule of events on the Days of Peace and Remembrance web page, park calendar, and Facebook page.
