Quite an awesome atomic discovery while exploring colleges for my daughter. This nuclear landmark is nestled in the University of Chicago campus. A great place to start any Atomic Tourism road trip!

The bulbous bronze Henry Moore sculpture and historical plaques mark the spot where Manhattan project scientists, government-funded and working in secret, coaxed the first self-sustaining nuclear chain reaction out of Chicago Pile-1. It happened on December 2, 1942.
