Imagine walking down an ordinary street in a big city while, deep beneath your feet, another city lies hidden—with real shops, sidewalks, and even old signs. Sounds like something from a fairy tale? But it is completely real, and this remarkable place is in the American city of Seattle. The whole story began with a simple accident and a devastating fire.
The Fire That Started with a Pot of Glue
On the summer day of June 6, 1889, a worker in a small workshop in downtown Seattle was heating woodworking glue over a fire. The glue suddenly caught fire, and the flames spread to nearby wood shavings. At the time, almost all of Seattle was built from wood—houses, sidewalks, and even water pipes! The city was like one enormous pile of kindling, ready to catch fire at any moment.
The fire spread incredibly quickly. People tried to put it out with buckets and even dynamite (yes, they blew up buildings to keep the flames from spreading!), but nothing worked. Within a few hours, more than 25 city blocks had burned down—nearly the entire business district. Fortunately, no one was killed, but Seattle was reduced to smoldering ashes.
It seemed like a terrible tragedy. Yet, surprisingly, this very fire gave the city a chance to become better.
The Idea That Changed the City Forever
When Seattle’s residents began thinking about rebuilding the city, engineers faced one major problem. Seattle’s streets had been built right beside the water, and high tides often flooded them. The sewer system worked poorly, and sometimes toilet water even flowed... upward, straight into people’s homes! Can you imagine how unpleasant that was?
So the city’s engineers proposed a bold solution: raise the streets by several meters—sometimes as high as one story, and in some places even two! It was as if you decided to raise the floor of your dollhouse so that water from the basement could never flood the rooms again.
But waiting for the new elevated streets to be built would take too long—businesses needed to reopen immediately. So shop owners first rebuilt their new brick buildings at the old ground level, while the streets were raised gradually afterward. As a result, the stores’ first floors ended up looking as if they were at the bottom of a deep trench between the high stone walls of the new sidewalks.
One Seattle resident wrote in a letter at the time:
“Every morning we wake up without knowing whether our street will have grown another meter overnight. It is like a city that has decided to grow taller, just like a child stretching upward!”
The Mystery of the Old Storefronts
What happened to those first floors left below street level? They were simply... left underground! Over time, new sidewalks were built above them, while the old shop entrances, staircases, and display windows were buried beneath the city. The result was a series of genuine underground passageways—dark and dusty, but filled with history.
For a long time, almost no one remembered them. The underground spaces were used as storage areas, and in the 1900s, city authorities even sealed them off completely, fearing fires and rodents. But in the 1960s, a history enthusiast named Bill Speidel decided that everyone should learn about this remarkable place. He organized tours beneath the streets and told visitors the story of the fire and the underground city.
Today, visitors to Seattle can buy a ticket for a real underground tour—the Seattle Underground Tour—and see old shop windows, glass sidewalks (yes, glass panels were once built into sidewalks so that light could reach below!), and even fragments of the era when the city decided to grow taller.

The Lesson Hidden Underground
Seattle’s history teaches us something remarkable: sometimes the most frightening event can become the beginning of something new and even beautiful. Without that fire, the city might have remained wooden, low-lying, and constantly flooded. Thanks to the bold decision to raise the streets, Seattle became safer and sturdier—and gave the world one of its most unusual attractions: a real ghost city beneath its own streets.
So, if you ever find yourself in Seattle, don’t forget to go underground—to the place where old brick walls still remember that hot June day in 1889, when a small pot of glue accidentally changed the history of an entire city.
