Seattle's Pioneer Square--home of "Underground Seattle," the great 1889 fire, and once the provisioner of supplies for gold seekers during the Klondike gold rush--is today a destination for millions of locals and visitors each year. This was the homeland of Chief Sealth's Duwamish and Suquamish tribes prior to the arrival of new settlers in the 1850s, though the area's landscape and shoreline are drastically different today. Doc Maynard, Arthur Denny, and Henry Yesler, among others, were catalysts who created much of the social, economic, and environmental change that established Seattle as the largest city in the region. Pioneer Square, located on the shores of Puget Sound's Elliott Bay, is Seattle's oldest neighborhood.
