Seattle Underground

Once a thriving street-level neighborhood, the places that make up the Seattle Underground were covered by elevated buildings after a major fire sparked redevelopment in the late 19th century. As the city grew up around it, the Underground eventually became home to hidden flophouses, illegal gambling and opium dens, and prohibition-era speakeasies. A local entrepreneur first started offering tours of these abandoned places more than 50 years ago.
