Seattle Underground

We went with Chris and Sarah on the Seattle Underground Tour. It was really interesting, who knew? I didn’t.

These were like sky lights in the city sidewalks. They were made with purple glass because before WWII glass was clarified with magnesium causing it to turn purple until they realized it was needed for steel production.

There site describes it better than I ever could.

BILL SPEIDEL’S UNDERGROUND TOUR is a leisurely, guided walking tour beneath Seattle’s sidewalks and streets. As you roam the subterranean passages that once were the main roadways and first-floor storefronts of old downtown Seattle, our guides regale you with the stories our pioneers didn’t want you to hear. It’s history with a twist!
