A historic view in Pioneer Square, the smokestack at the Seattle Steam Plant.Located at 619 Western Avenue, the smokestack stands out among the red brick buildings and odd against the sleek facades of the new skyscrapers in downtown Seattle. Built in 1893, after the Great Seattle Fire in 1889, it was one of many buildings that rose out of the ashes in the Pioneer Square District (what at that time was downtown Seattle). Originally serving about 30 buildings, it now serves nearly 200 buildings with steam for heat and hot water. It is a working remnant of the industrial era not only in Seattle, but in the nation.
