Cape Canaveral Vehicle Assembly Building, Florida

Really big rockets, like the Saturn V, which took men to the moon, were developed at places like NASA’s Marshall Space Center in Alabama, where their engines were tested on outdoor stands. Launching was mostly done at Cape Canaveral, where rockets would arrive in separate pieces from manufacturers, then assembled at the launch site. This was done in a large vertical building, the Vehicle Assembly Building, which is still there. Since it was vertical, it has a relatively small footprint, 348,000 square feet, but is 526 feet tall, and encloses 130,000,000 cubic feet, making it among the largest buildings in the nation. It is the tallest single-story building in the nation, and the tallest building outside of a metropolitan center.
