Underground Tour

Pioneer Square

Seattle, Washington

608 1st Ave

Bill Speidel's Underground Tour is a popular Seattle attraction located in its historic Pioneer Square neighborhood. After area streets were raised a floor or more with retaining walls that separated the streets from the sidewalks. Buildings had to accomodate this, creating second floor entrances at the new street level, and new sidewalks capped the gap between streets and buildings. The result was a number of underground "tunnels", passageways that follow the original sidewalks.

Bill and Shirley Speidel began giving tours through these passages into Seattle's history as part of an effort to preserve the Pioneer Square neighborhood, presenting well-researched history in a fun and informative way as groups walk their way through some of the tunnels and old store rooms. The preservation effort was a success - Pioneer Square became Seattle's first neighborhood to be listed on the National Register of Historic Places.
