Beneath the Streets: Hollow Sidewalks and Historic Passageways

Seattle has an entire city hidden beneath its streets—literally. Travel back in time to Seattle’s historic birthplace in Pioneer Square. Rebuilt in the late 1800s following the Great Fire, the neighborhood is built on top of an older streetscape creating unusual challenges, including hollow streets and sidewalks, and also an opportunity for historic discovery through a fascinating underground labyrinth. We’ll travel to Pioneer Square via the transit tunnel, then explore under the sidewalks with professional, entertaining, guides.
