Go underground on a 1-hour walking history tour through Seattle's original area. Our experienced guides lead small groups through, and beneath, Pioneer Square to the street level that existed in the 1890s. Explore underground pathways that were built more than 120 years ago, learning details on early Seattle history, why these spaces were built, and how they have been used (and misused) over the years. Marvel at how this once Indian encampment has since transformed into one of the 20 largest cities in the United States.
