Tour the underworld of Seattle
Ever wanted to see what lies below the streets of a big city? This tour is your big opportunity! Explore parts of Seattle that were once the streets of Seattle, before it became the big city that it is today! Your tour guide will give you all the stories of what once was- the good, the bad and even the hilarious.
The reason for this "underground city" that you will tour is that when Seattle was originally built, it was put up on muddy tide flats which would flood on a regular basis. After the great fire of Seattle the city decided to rebuild- but only with concrete and masonry buildings. At the same time they decided to raise the streets up one whole story. They built retaining walls on both sides of the streets. They filled in everything between those walls and then paved it over. Thus raising the streets (and creating the underground world you will soon discover).
