Hit Bob Speidel's Underground Tour yesterday. Great tour of some of the underground that was created after the great Seattle fire of 1889. After the fire the city wanted to raise the ground level to avoid all the problems being on such low ground caused. That plan was going to take too long so the business started rebuilding at the original ground level. They had to plan on their second story becoming their main entrance as the city build the streets and its property up higher. Eventually, the businesses and city built new sidewalks at the new level but the original level remained in use for a long time and some still are. Eventually, a lot of it was sealed off and left to decay until Bob Speidel broke into them and started doing tours as part of an effort to help raise awareness and get Pioneer Square declared a protected historic site. The tours have been going strong for over 50 years now.
