Bill Speidel's Underground Tour is Seattle's best history lecture disguised as a walk through a basement: seventy-five minutes beneath Pioneer Square's sidewalks, through the buried storefronts, passageways, and purple-glass skylights of the city that existed before the Great Fire of 1889 — after which Seattle, tired of tideflat sewage physics (the guides' toilet-geyser material is foundational), simply rebuilt its streets one story higher, entombing the old ground floors as the underground. The tour's DNA is irreverent by charter: Speidel, a muckraking columnist, launched it in 1965 to fund Pioneer Square's preservation (it worked — the district's historic designation owes him), and the guide corps maintains his register — the city's founding told through its scoundrels, with Doc Maynard the generous drunk, the sewage engineering farce, the Klondike hustle, and the seamstresses-of-no-sewing economy of the old Skid Road given their full comic and genuine historical weight. The route alternates street level and three underground stretches (uneven floors, dust, the occasional resident rat playing itself), surfacing finally in the gift shop's saloon-adjacent cheer. It runs hourly, rain-proof by definition, kid-tolerant while winking over their heads, and pairs by design with the square above: Smith Tower's elevators two blocks on, the totem and pergola, and the Klondike museum (free, superb) around the corner. Book the first or last tours for thinner groups, wear real shoes, and accept the premise — the truest Seattle origin story is the one told from under the sidewalk, looking up through the purple glass.
The history under the jokes is real and load-bearing. Pioneer Square was the city: the 1852 settlement's commercial heart, built on sawdust-filled tideflats where high tide reversed the plumbing (the crowd-pleasing geyser stories are documented) and the streets flooded on schedule. The June 1889 fire — a glue pot, a cabinet shop, twenty-five blocks gone in an afternoon — gave the city its reset: ordinances required masonry and, critically, raised the street grades one to two stories to beat the tides, producing the decade-long absurdity the tour relishes, when sidewalks ran at old level beside new streets a story up, ladders connected them, and pedestrians occasionally fell to their deaths in what newspapers called involuntary sidewalk suicide. By the mid-1890s the sidewalks bridged over, the old ground floors became basements and then sealed voids, and the underground's second life began — storage, speakeasies, opium dens, and the quarantine-era sealing that left it to the rats until Speidel's 1965 resurrection.
The tour's route works three excavated stretches beneath Pioneer Square's blocks — brick arches, dead storefronts with their glass intact, the banked earth of the old street line, and the amethyst skylights (glass prisms set in the sidewalks above, turned purple by decades of sun on manganese) that light the passages in submarine violet. Guides run licensed-comic style with genuine scholarship underneath: the Maynard-versus-Denny founding temperaments, Henry Yesler's mill and the original Skid Road's logging etymology (and its slide into the national idiom), the Klondike outfitting boom that built the square's surviving architecture, and the underground's own afterlife told artifact by artifact.
Practicals: seventy-five minutes, hourly departures from Doc Maynard's public house on the square, advance booking smart in summer and on rainy weekends (the tour is the city's agreed wet-day plan); surfaces are uneven and stairs are involved — real shoes, modest mobility demands, strollers checked. Kids from about eight ride the humor's surface happily while the innuendo sails overhead by design; teens get the full material. The pairing logic is built in: Klondike Gold Rush National Historical Park's free museum (the fire-and-boom story told straight, two blocks away) before or after, Smith Tower's elevators as the vertical punchline, and the square's totem, pergola, and galleries between. Speidel's final joke stands: the tour that began as a preservation fundraiser became the district's economic anchor — the buried city now holds up the living one in both directions.
What to Expect
- The experience
- A 75-minute guided walk through three buried stretches of pre-1889 Seattle beneath Pioneer Square — storefronts, passageways, purple skylights — told in the founding scoundrels' register.
- Best time
- First or last tours of the day for thinner groups; it is the city's consensus rainy-day plan, so book ahead on wet weekends.
- How long
- Seventy-five minutes plus the square's pairings.
- Tips
- Real shoes — floors are 1880s. Kids eight-up ride the humor's surface; the innuendo sails overhead by design. Stack the free Klondike museum and Smith Tower after. Look up through the purple glass.
Good Questions
Is the underground real?
Entirely — after the 1889 fire the city raised its streets a story, burying the old sidewalks and ground floors. The tour walks three excavated stretches, original storefront glass and all.
Why are the skylights purple?
The sidewalk prisms that lit the passages contain manganese glass, turned amethyst by decades of sun — the underground's signature violet glow is a chemistry accident.
Is it appropriate for kids?
By design — the script runs two registers, with the bawdy history winking over young heads. Eight-up enjoy it; floors and stairs set the practical limit.
Do we need to book ahead?
Summer and rainy weekends, yes — it is the city's agreed wet-day plan and tours cap. First and last departures run thinnest.
What should we pair it with?
The free Klondike Gold Rush museum tells the same era straight two blocks away; Smith Tower's operator elevators are the vertical punchline; Sky View crowns the stack four blocks north.
Pairs Well With
Smith Tower
The 1914 original — once the tallest west of the Mississippi, with brass-caged elevators run by operators, a Prohibition-themed bar in the old Chinese Room, and the open-air deck's wraparound ironwork over Pioneer Square.
Sky View Observatory
The tallest public observatory on the West Coast — floor-to-ceiling glass on the Columbia Center's 73rd floor, 902 feet over downtown, with the Space Needle BELOW you and Rainier filling the south wall. The locals' view.
Pike Place Market
America's oldest continuously running public market — flying fish, the original Starbucks, buskers under the clock, a gum wall in the alley, and nine acres of stalls stacked down the hillside to the bay. Free, daily, essential.
