Believe it or not, the world’s biggest building (measured by usable space by volume) is right here in Washington. It’s the Boeing Everett Factory, and considering it’s used to assemble airplanes, it makes sense that it’s massive. And believe it or not, you can take a tour and see it for yourself.

Plans for this factory were first announced in 1966.

After winning a $525 million contract from Pan American World Airways, Boeing purchased 780 acres north of the then little-used Paine Field. Factory tours were first offered in 1968 with the first roll-out of the 747.
