Once upon a time, World’s Fairs were the biggest events on the planet. They were places where people could walk through futuristic buildings, try new inventions, and see things they’d never seen before.

Many of these events happened over a hundred years ago, and most people don’t think about them today. But their impact? Still here—and often hiding in plain sight.

This fair introduced the Ferris wheel, which many called the answer to France’s Eiffel Tower. Its white buildings, lit by electric lights, stunned visitors who had never seen anything so bright.

It wasn’t just a show—it changed architecture across the country. The layout inspired how future cities were planned, with wide boulevards and organized park systems.

Even the term “midway” came from this event and stuck around for carnivals and fairs.

What started as a fair to celebrate the Panama Canal ended up giving San Diego its most beautiful public space. Balboa Park was supposed to be temporary, but people loved the Spanish-style buildings so much, they stayed.

Today it’s full of museums, gardens, and theaters. Without this fair, that land might have been used for factories or housing.

The event gave the city both beauty and identity.

The Electric Tower stood as a symbol of that promise.
