Imagine walking down an ordinary street, going into a shop for ice cream — and then realizing that right under your feet there’s another street. With old storefronts, sidewalks, and even doors that nobody had opened for more than a hundred years. That’s exactly how Seattle is: a city with a secret lower level.
The fire that changed everything
In 1889, Seattle suffered a real disaster. A carpenter accidentally knocked over a kettle of hot glue, and a fire broke out. Wooden buildings caught fire one after another, like matchsticks. In just a few hours, the flames destroyed almost the entire downtown area.
Residents could have simply left and started over somewhere else. But they chose otherwise: to rebuild the city from scratch, and make it better than before. Engineers came up with a daring plan — to lift the streets up by an entire floor. Why? Because the old city sat too low by the sea, and every time the tide came in, the streets flooded. It was awful and deeply inconvenient, especially for toilets (yes, back then toilets worked nothing like they do now, and seawater created huge problems).
Workers piled up mountains of earth and built new sidewalks and roads directly over the old ones. The old first floors of buildings ended up underground. What resulted was something incredible: a whole ghost town hidden in the dark.
Life in the underground
At first, people continued to use the old underground sidewalks. Picture this: you walk along a street, then go down a set of stairs — and you find yourself in a dim corridor lined on both sides with shops. Overhead, there are glass tiles in the pavement that let in a violet light. Some residents even said that, as children, they ran through these tunnels, cutting across from one block to another.
“We knew all the entrances and exits,” an elderly Seattle resident said in archival recordings from the early 20th century. “It was our secret place — one that adults tried not to think about.”
But over time, the underground sidewalks became dangerous. Some ceilings started leaking, there was no proper lighting, and in 1907 the authorities officially shut down the underground city. The entrances were boarded up. People began to forget that anything existed down there at all.
The man who kept the city from being forgotten
More than fifty years passed. In the 1960s, a journalist and historian named Bill Speidel learned that city officials were planning to demolish old buildings in downtown Seattle. With the buildings, the entrances to the underground city would disappear too — forever.
Bill was a man with a huge sense of humor and a genuine love of history. He began taking people underground himself — with a flashlight, telling funny and scary stories about old Seattle. The tours became incredibly popular. Suddenly, city residents realized that a real treasure was hidden right beneath their feet!
In 1965, Bill founded the official “Bill Speidel’s Underground Tours” — and they’re still running today. Every year, thousands of people descend underground to walk along those same sidewalks where residents of old Seattle had been going more than a hundred years ago. The glass tiles in the ceiling still let light through — now from the bottom up, like little purple stars.
Why this matters for you
Want to know the most surprising thing about this story? Underground Seattle is like a secret level in a video game — only it’s real. And it almost got destroyed simply because grown-ups decided the old stuff wasn’t needed anymore.
But one person — Bill Speidel — decided it had to be preserved. He wasn’t a mayor, and he wasn’t rich. He simply loved stories and knew how to tell them in a way that made other people fall in love with the past too.
Cities are like living creatures. They have their own memory, tucked away in old walls, sidewalks, and underground corridors. And sometimes, to keep that memory alive, you only need one curious person with a flashlight — someone who isn’t afraid to step down into the dark.
Maybe that person will be you someday.
