The Manhattan Project National Historical Park (MAPR) is one of the nation’s newest parks. Established in 2015, MAPR comprises three distinct sites in Washington, Tennessee, and New Mexico. These sites led the effort to build a bomb to end World War II. Each one made incredible advances to the science, manufacturing, and engineering that ushered the globe into the “atomic age.”
Here in Los Alamos, New Mexico, about 30 landmarks are officially part of MAPR. Many of these places, like J. Robert Oppenheimer’s house, Ashley Pond, and Fuller Lodge, are publicly accessible.
The Manhattan Project National Historical Park encompasses 17 sites on Los Alamos National Laboratory property and 13 sites in downtown Los Alamos, where “Project Y” was centered during World War II.
