Manhattan Project National Historical Park, in partnership with Pearl Harbor National  Memorial, will host “Days of Peace and Remembrance” across its three sites and at Pearl Harbor to  commemorate and reflect on the 78th anniversary of the atomic bombings of Japan in 1945. This  commemorative programming acknowledges and interprets the conflicting viewpoints, both historical  and modern, that surround the development and use of the world’s first atomic weapons. These events  provide an opportunity to reflect on the historical and emotional traumas of the atomic  bombings. Messages of Peace programs will be held at each of the park sites over the next two weeks,  following is a schedule of events.  

Oak Ridge, Tennessee 

On August 6, 1945, the US Army Air Force dropped the uranium-fueled Little Boy atomic bomb over  Hiroshima in the first of only two nuclear bombings of a population in history. The Manhattan Project  facility at Oak Ridge produced the uranium used in the Little Boy bomb.    On August 6, the Park will host a sunrise (6:48 a.m. EDT) ceremony to commemorate the  78th anniversary of the atomic bombing of Hiroshima, Japan. The event will take place at  the International Friendship Bell in Bissell Park and will feature music from an Oak Ridge Civic Music  Association quartet. The ceremony will allow for somber, quiet reflection and the public is invited to ring  the bell for any reason that speaks to them. One hour before dawn park rangers will light luminarias that  have been decorated with messages of peace by community members. The luminarias will remain lit  throughout the event.  For those who are unable to attend the August 6 event in person a virtual bell ringing will be available  on the park’s event webpage from 6 a.m. EDT on August 6 through 11:59 p.m. PDT on August 9.

On August 7 from 7:30 p.m. to 9 p.m. MDT, the Park will host a Lights for Peace event at Ashley Pond  Park where luminarias with messages of peace written by the public will be lit along the path. The event  is designed to be a quiet, introspective experience, focused on providing the public with an opportunity  to walk the lighted path in silence and have their own reflective experience based on their personal  reasons for participating.  

The commemoration event will begin at 6:30 p.m. HST on August 8. The public will be able to help place  luminaries along the shoreline of Pearl Harbor and engage with National Park Service staff as they share  stories of the peace and reconciliation that grew out of the harrowing reality of World War II.
