The Seattle Underground is a network of underground passageways and basements in downtown Pioneer Square, Seattle, Washington, United States that were at ground level when the city was built in the mid-19th century. After the streets were elevated, these spaces fell into disuse, but have become a tourist attraction in recent decades.Download Download See more
