China Atomic City Memorial
中国原子城
The former site of China’s first nuclear weapons research base, where its atomic and hydrogen bombs were developed. The memorial hall tells this once-secret history.
Atomic City lies in Xihai Town, Haiyan County. It was originally known as State-Owned Factory 221 and was China’s first nuclear weapons research base. China’s first atomic bomb and first hydrogen bomb were researched and assembled here, and the base was decommissioned in 1995. The China Atomic City Memorial uses artifacts, photographs and reconstructed scenes to show how the base was built and to honor the scientists behind the “Two Bombs, One Satellite” program. Next door, the memorial park contains a monument and some original buildings. Admission to the memorial hall is free, but you need to bring your ID card, and it may be closed on Mondays. Xihai Town is a base for accommodation on the northern route, so you can plan it on the same day as Jinyintan Grassland and Jinsha Bay.
