Reminder: this is how American cities looked 100 years ago.
Everything in this image was demolished.
Here's why β and how we can bring it back... (thread) π§΅
At the turn of the 20th century, exhibitions known as World's Fairs transformed American cities into vast architectural displays.
They were moments of immense civic pride and confidence for the future...
For example, St. Louis turned its parks into lagoons and waterways, navigated by visitors on Venetian gondolas and electric boats.
1,500 neoclassical buildings built in a few years.
What for? Ultimately, it was to celebrate humanity.
World nations came together to showcase advances in culture and technology inside great "pavilions", like the Palace of Transportation in St. Louis:
World's Fairs were like the Olympics of their era, before the rise of TV broadcasting.
Countries took turns hosting and there was plenty of one-upmanship β especially as the geopolitical torch passed from Europe to the New World.
Fairs were even chances for cities to bounce back from disaster.
Chicago put on maybe the greatest ever event, just 22 years after being gutted by an inferno in which 17,000 buildings were destroyed...
Then, in 1893, it produced a fair attended by 27 million people β when Chicago's population was only 1 million and there was no air travel.
In just two years, the "White City" went up in Jackson Park.
Chicago did everything to upstage the previous fair in Paris, which had unveiled the Eiffel Tower.
1893 was a glimpse into the future: the first fair lit solely by electricity, which most Americans were witnessing for the first time.
Among the state-of-the-art technologies displayed was the world's largest telescope.
Above all, these fairs were expressions of confidence in face of fast, disconcerting industrial change.
In 1962, the Seattle fair was a statement of America's outer space ambitions, and the Space Needle built as a monument to that optimism.
Enthusiasm for the fairs waned in the mid century and they never got back to their former glory.
They still happen today, but even Dubai 2020 couldn't beat Chicago's attendance almost 130 years earlier.
And sadly, very little remains from the early fairs β it can be hard to believe they ever happened.
What happened to all the neoclassical wonders?
They were mostly temporary, built from pine with exteriors plastered on.
Most were dismantled, but some of those built from more solid materials linger on, like Chicago's Palace of Fine Arts.
As well as technology, the fairs reminded people that buildings could be expressions of inward greatness.
They sparked the "City Beautiful movement": a short-lived philosophy that said architectural beauty could improve social cohesion.
If the early fairs were driven by one thing, it was civilizational optimism β captured in Chicago's 65-foot crowning monument.
They didn't always make economic sense, but were funded by private donations to go ahead anyway.
Can we bring them back?
Renewing the glory of the fairs might be a way to unite people in a sense of cultural and techno-optimism β when much about the world seems uncertain...

Most people don't realize how mysterious the Pyramids truly are.
They're so old that Cleopatra lived closer to us than to their construction β yet Khufu's Pyramid is so precise it aligns north within 1/20th of a degree.
Some more mind-blowing facts about themβ¦ π§΅
They're not just incredibly old, but impossibly precise.
The Great Pyramid (attributed to Khufu, c.2550 BC) is 3.4 arcminutes off perfect alignment with true north. That's precision of ~1 millimeter per meter of the length of its base.
Executing such accuracy on something with a 13 acre footprint is astounding β how did they do it?
Possibly with the help of the sun on the equinox, which on that day rises exactly in the east (and sets perfectly in the west)...
This 2,700-year-old tablet is the oldest map of the world.
It reveals just how differently the ancients understood the world β but one detail is particularly strange.
It sheds light on a VERY ancient storyβ¦ (thread) π§΅
The "Imago Mundi" is the oldest map of the world β as it was known to the Babylonians around 700 BC.
It's carved into a small piece of clay, with annotations explaining it, and the creation myth of the world.
The central parts of the map are easy to read:
The Euphrates river runs north to south, straddled by the city of Babylon (modern-day Iraq), and surrounded by cities and regions marked by small circles.
We often hear about the 7 Wonders of the World, both ancient and modern.
But what about wonders of the Medieval Age?
Here are seven β and what happened to them... π§΅
There's no "official" list of wonders built in the Middle Ages like for antiquity. The 7 ancient wonders list was proposed by Ancient Greeks, and endured to today.
So here are suggestions β sadly, most are long lost to time...
1. Old London Bridge
By all measures considered a world wonder by medieval Europeans. "Living bridges" were common in the Middle Ages and London's was the greatest β people even flocked to it for religious pilgrimage.
