Inscription. In 1943, this site was the east entry gate to the "secret city" of Los Alamos, home of the Manhattan Project, which required credentials for entry until 1957.

In 1986, Sunrise Kiwanis recognized the need for a place for campers to park while visiting Los Alamos and adopted the park. Over the years, the Kiwanis Club held raffles to raise $30,000 to help improve the site and provided hundreds of hours of volunteer labor. With an additional $12,000 from the State of New Mexico, Sunrise Park was born.

Sunrise Park was recognized in 1986 with a Certificate of Merit awarded to Sunrise Kiwanis for its efforts to help Beautify America. This prestigious award was presented by the Secretary of the Interior, Don Paul Hodel, and was one of only fifty such awards given at the time.

In 2001, Sunrise Kiwanis joined with the Kiwanis Club of Los Alamos to become one organization which continues to help maintain the park you see here today. In 2016, the Los Alamos County Council passed a resolution officially renaming Sunrise Park to Los Alamos Project Main Gate Park.

The replica of the main gate guard shack was added to the park in 2015 and is a popular photo opportunity with visitors.

This building is a re-creation of the historic security gate all Manhattan Project workers passed through to enter Los Alamos. Before reaching the security gate, however, newcomers to Project Y had to go through Dorothy McKibbin. Known as the gatekeeper of Los Alamos, Dr. J. Robert Oppenheimer hired her as his assistant in Santa Fe, where she organized housing, greeted scientists, and, perhaps most importantly, issued security and identification passes to Project Y workers.
