The world's first atomic bomb, in unassembled pieces, traveled through Belen in July 1945 en route to the Trinity site at what is now White Sands Missile Range. The bomb's Belen route used old Highway 85, now Highway 314, also known as Main Street. Located in downtown Belen in 1945 was Roy's Cafe, a restaurant where military and science personnel would go to grab a meal, since it had the necessary security clearance. Local legend suggests personnel escorting the atomic bomb, and perhaps the bomb itself, stopped at Roy's Cafe as they passed through town.
