Did You Know?
A Building So Big It Rained Inside
1. The largest building in the world by volume is thirty-five kilometres north of Seattle.
Boeing's Everett factory holds the Guinness record at 472,370,319 cubic feet — about 13.4 million cubic metres — under one roof. The floor covers 98.3 acres, enough to fit the whole of Disneyland park, or 75 American football fields.
It was built in 1967 for the 747, whose 196-foot wingspan would not fit in any existing Boeing plant. Inside there are 26 overhead cranes running on more than 30 miles of track, and six doors on the south face, four of them 82 feet high and 300 feet wide. Around 30,000 people work there. The site has its own fire department, medical clinic, daycare and water treatment plant.
2. When it opened, the building generated its own weather.
The story goes that the volume was large enough for warm, moist air to collect under the ceiling and form clouds, and that it rained indoors until circulation equipment was installed to stop it.
3. More than 5,000 wide-body aircraft have been assembled in it.
Including over 1,500 Boeing 747s, before that production line closed in 2022. The factory now builds the 767, 777 and 777X — and, since July 2026, the 737 MAX as well.
4. One coffee shop opened here in 1971 and there are now more than 40,000 of them.
Starbucks opened beside Pike Place Market on 30 March 1971, selling roasted beans and equipment. It had 17 stores in 1987, 84 in 1990, 165 when it went public in 1992, 425 in 1994, and passed a thousand in 1996. There are now more than 40,000 locations in over 80 countries.
One honest correction, because it is the kind of fact everyone repeats: Seattle no longer has the most coffee shops per capita in the United States. It keeps the reputation, and the headquarters, but not the ranking.
The clock: Seattle sits at about 122° west on Pacific Time, within roughly nine minutes of its own solar noon — well aligned, like San Francisco.
What is not steady is the daylight. At 47.6° north, Seattle runs from around sixteen hours of light at midsummer down to roughly eight and a half in December — a swing of some seven and a half hours across the year.
So: a city whose two defining industries are a shed large enough to make its own rain, and a shop that turned coffee into a chain of forty thousand. Both started small, in Seattle.
