Honestly, if you could hop in a time machine and visit any single year in history, it would be a mistake not to pick 1900. Specifically, April to November. Paris was literally glowing. While we often think of the turn of the century as some dusty, sepia-toned era of horse carriages and stiff collars, the Paris Exposition of 1900 was basically the birth of the 21st century. It wasn't just a fair. It was a 540-acre flex.
France spent roughly 100 million francs to turn the banks of the Seine into a psychedelic vision of the future. It’s wild to think about, but over 50 million people showed up. To put that in perspective, the population of France at the time was only about 39 million. People traveled from every corner of the globe to see things we take for granted now—like escalators and movies.
Most people assume the Eiffel Tower was the star of the show, but that’s a common misconception. The tower was actually a "leftover" from the 1889 fair. By 1900, it was already eleven years old. The real star? Electricity. Specifically, the Palais de l’Électricité. It was a massive, ornate building covered in 5,000 multi-colored incandescent lamps. At night, it looked like something out of a dream, casting a light so bright it reportedly made the moon look dim.
The Moving Sidewalk and the Death of the Horse
One of the weirdest and most practical inventions at the Paris Exposition of 1900 was the Rue de l'Avenir—the Street of the Future. It was a three-tier moving sidewalk that circled the entire grounds.
Think about that for a second.

This wasn't just a slow conveyor belt at an airport. It was a high-speed (well, 5 miles per hour) wooden platform that moved people across the city. It used a system of rotating wheels and electric motors that felt like magic to people who were used to walking through mud and manure. It carried up to 14,000 people at a time. Some visitors actually got "sidewalk sick" because they weren't used to the sensation of moving without walking. It’s kind of funny to imagine Victorian gentlemen in top hats stumbling around because the ground was moving under them.
A Technical Revolution Hidden in Art Nouveau
While the architecture was all swirly, organic Art Nouveau—think the iconic Metro entrances designed by Hector Guimard—the guts of the fair were pure engineering. This was where the world first saw the Diesel engine. Rudolf Diesel showed off his new creation, and get this: it ran on peanut oil. He genuinely believed his engine would help small farmers and independent industries. History obviously took a different turn with petroleum, but the seed was planted right there in Paris.
Then there was the "Telegraphone."
Valdemar Poulsen, a Danish engineer, demonstrated the first-ever magnetic wire recorder. It was the great-grandfather of the cassette tape and the hard drive. People could record their voices onto a wire and play it back. Imagine the look on a visitor's face in 1900 hearing their own voice for the first time. It must have felt like a haunting.
And we can’t forget the Campbell’s Soup gold medal. You know that little gold seal on every can of tomato soup in your pantry? It’s not just a marketing gimmick. They actually won that at the Paris Exposition of 1900. It’s one of those weird bits of history that sits in our kitchen cabinets every day.

The Darker Side: Human Zoos and Colonialism
It’s easy to get swept up in the romanticism of the Belle Époque, but the fair had a deeply uncomfortable side that historians like Pascal Blanchard have spent years documenting. The "Colonial Section" was massive. France, along with other European powers, wanted to show off their empires. This included "human zoos"—replicated villages where people from Africa, Asia, and the Pacific were essentially put on display like museum exhibits.
Visitors would walk through these mock villages to gawk at people performing "daily tasks." It’s a stark, painful reminder that while the fair celebrated technological progress, social progress was lagging way behind. The exposition was designed to justify colonialism by framing it as a "civilizing mission." It’s a nuance that often gets skipped in travel brochures, but you can’t understand the 1900 fair without acknowledging the exploitation that funded much of it.
Cinema and the Giant Telescope
The Paris Exposition of 1900 was also the moment film went mainstream. The Lumière brothers projected their films on a screen so large—roughly 70 by 50 feet—that a crowd of 25,000 could watch at once. They had to keep the screen wet so the image would be bright enough.
Meanwhile, at the Palais de l’Optique, they built the "Great Paris Exhibition Telescope of 1900." It was the largest refracting telescope ever made. The lens alone was 49 inches in diameter. It was so heavy it couldn't be moved to track the stars; instead, they used a massive 2-meter mirror called a siderostat to reflect the sky into the fixed tube. It was a bit of a failure, honestly. It was too big to be practical and was scrapped shortly after the fair, but the ambition behind it was staggering.

Why 1900 Still Matters to You
You can still see the bones of the fair today. If you’ve ever stood on the Pont Alexandre III, you’re standing on a piece of the 1900 exposition. It was built specifically to celebrate the new Franco-Russian alliance and to provide a grand entrance to the fair. The Grand Palais and the Petit Palais? Also built for the 1900 fair. They weren't intended to be temporary. They were built to last, meant to prove that Paris was the center of the civilized world.
The Paris Exposition of 1900 basically drew the blueprint for the modern world. It gave us the concept of a globalized culture, where technology, art, and commerce all collide in one place. It was the last time the world felt a sense of unbridled optimism before the world wars changed everything.
Actionable Insights for History Buffs and Travelers
If you want to experience the ghost of the 1900 exposition today, don't just go to the Eiffel Tower. Here is how to actually find the fair in modern Paris:
- Visit the Musée d'Orsay: While the building itself was a train station (Gare d'Orsay) built for the 1900 fair, the collection inside holds many of the Art Nouveau masterpieces that debuted during that summer.
- Walk the Pont Alexandre III at Dusk: This is arguably the most beautiful bridge in the world. Look at the lampposts; they were the height of "electric" luxury in 1900.
- Find the Guimard Metro Entrances: Head to the Abbesses or Châtelet stations. These green, cast-iron structures are the literal DNA of the fair's aesthetic.
- Check out the Petit Palais: It’s free to enter the permanent collection. The architecture inside is a perfect time capsule of the 1900 "Beaux-Arts" style.
- Read "The Greater Journey" by David McCullough: It provides incredible context on how Americans experienced Paris during this era, though it spans a wider timeframe.
The exposition wasn't just a party. It was a transition. It was the moment we stopped looking at the ground and started looking at the wires overhead. It was messy, it was beautiful, and in many ways, we are still living in the world it built.
