The National Park Service (NPS) and the Department of Energy have collaborated in opening three historical spots where atomic bombs in the U.S. were first made. Called as the Manhattan Project, the sites are part of a program going against the Axis Powers in the height of World War II.

The Manhattan Project NHP at New, Mexico, Los Alamos is highly remote, and there's no public access to these sites except by walking tours. Their laboratories were split into three parks which consist of the Gun Site Facilities that accompanied in the creation of the "Little Boy" bomb. Meanwhile, their V-Site Facilities are where scientists used to assemble Trinity devices, and the Pajarito Site was used for plutonium chemistry research.

At the same time, the administrative and military headquarters of the Manhattan Project will be opened to the public in the Oak Ridge Reservation. The area was also used in research and experimentations of uranium and plutonium chemicals, including the creation of uranium bombs. Locations to be visited include the X-10 Graphite Reactor, Y-12 New Hope History Center and the former K-25 gas building among many others.

In the capital of the country, the Hanford Engineer Works Project site created a massive amount of plutonium and also had irradiated uranium fuel. It consists of the B-Reactor National Historic Landmark Washington which made materials and chemicals for the Trinity test and plutonium bombs.

Many people were tense regarding the NPS projects. But, in an interview with Fox News, the NPS said they do not want to make a statement whether atomic bombs were either right or wrong, but the initiative was simple to commemorate U.S. history.

Charles Strickfaden, Manager of NPS' Los Alamos Site told reporters: "We don't go back to rewrite history, we just tell from the historical documents, from government documents, and from our communities what the nation and the public was feeling then. And we leave it up to our public and our visitors to determine their own version on how the feel about the atomic bomb them and how they feel about nuclear technology today."
