The Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida is the world’s fourth largest building by volume. Completed in 1966, the VAB also holds the record of the largest one-story building in the world and the tallest building outside an urban center in the United States.

The VAB is so large, in fact, that it has its own weather. On humid days, rain clouds can form below the ceiling, requiring about 10,000 tons of air conditioning equipment to control the moisture. With this setup, the total volume of air in the building can be replaced in only one hour.
