Welcome to the “Secret City”
Tucked between the mighty Columbia River and the arid Rattlesnake Hills of Southeastern Washington State are a collection of communities bound together by one of mankind's most ambitious feats, the Manhattan Project. Today, this region is known as the Hanford and Tri-Cities area, and offers a glimpse into the massive undertaking of the 1940's that brought an end to World War II and began a new era of implications and opportunity.
