Seattle Underground ghost lore (Pioneer Square)

The Seattle Underground is a network of subterranean passageways and basements beneath Pioneer Square created after the 1889 Great Seattle Fire and the subsequent raising of street levels. Bill Speidel's Underground Tour, which departs from a storefront in Pioneer Square, presents historical information alongside local ghost stories and urban legends about the underground spaces. The existence of the underground streets and building remnants is documented; claims of hauntings are anecdotal and promoted as entertainment on guided tours. The site ties directly to the documented 1889 fire and the city’s rebuilding efforts.
