Out of an abundance of caution, the Manhattan Project National Historical Park Visitor Center is closed to the public until further notice. Registration for public tours of Hanford’s Manhattan Project National Historical Park facilities has also been postponed. Thank you for your understanding and support. Updates will be posted on our website, https://manhattanprojectbreactor.hanford.gov/.
At the start of Manhattan Project work, about 1,500 residents in the agricultural towns of Hanford and White Bluffs were displaced from their homesteads and orchards, along with Native American Tribes, as the government transformed the Eastern Washington desert as part of the secret war project. Sign up for a tour and learn more about the history of the mid-Columbia prior to the eviction of the homeowners and tribes in 1943.
The U.S. Department of Energy offers free public tours of the pre-War historic sites.
Tour season is generally from spring to fall, with varying dates and times. The list of tour dates for 2020 will be posted by early March.
