Well, what if beneath that famed Pioneer Square you just traversed was an altogether different side of Seattle, one filled with a labyrinth of Seattle history, damp caves, and even the true origins of Seattle’s first buildings? This underground city is not just storybook stuff. No, the Seattle Underground is very much real and is a network of underground passageways and basements in downtown Seattle.
The story? On June 6th, 1889 a fire razed 31 blocks of the Pioneer Square region of downtown Seattle. The builders, in hindsight, saw the need to build the new buildings as brick and mortar instead of wood, and chose not to build the new structures in what was tidal floodplains.
The Seattle Underground is now available and open to the public to view. Interested visitors can meander through old decrepit banks, hotels, and even the underbelly of those walking the sidewalks above you. And if you’re down under Pioneer Square and chance to find someone who knows a bit about this mysterious section of Seattle, be sure to ask them about the more cloak-and-dagger history of this oft-forgotten spot. Many a tale, both fictitious and factual are circulated about this mysterious labyrinth, and whether they’re true or not, there’s a lot to be found in Seattle’s underground.
