Make your way to Seattle’s Underground Tour to learn more about this historic city. The basement passageways below was Seattle’s original ground level in the mid 19th century. An accidental fire spread destroyed 31 blocks of Seattle due to initial wooden foundation. Instead of rebuilding the city, the townspeople decided to build above the original ground level due to frequent floods from high tide.
Below is a portrait of Seattle before the town caught fire.
After the rebuild, a lot of merchants moved up to the new ground level leaving all the rubble behind. The underground is closed to the general public except for special occasions such as these Underground Tours.
After the rebuild some merchants operated on the new ground level but some decided to operate on the original level still. These glass panels were put in place to allow light to the underground. If you’re walking along the sidewalks and you spot some random glass panels, you know there is an underground passageway underneath.
