Did you ever wonder what's under the city streets that you walk on every day? Well if you live in Seattle, you would be surprised to find out what lies underneath! Underneath the streets of the Pioneer Square neighborhood lies the Seattle Underground, a hidden section of passageways and corridors which at one time hosted an array of commerce both legal and illegal as well as shops, homes, storage and a collection of fascinating history unknown to most, even among Seattle's citizens themselves. As a result of Seattle's reconstruction following the Great Fire of 1889, the streets were lifted several stories above ground level for several reasons, leaving all the surrounding buildings to partially dwell underground. After only a few decades the city shut down the Underground for public health and safety concerns but some areas remained in use for various nefarious activities while the rest were left abandoned. While the Seattle Underground is now nothing but a tourist attraction, there persists a long and interesting history hidden underneath these streets, much like the Underground itself.

But it wasn't always this easy and this fast. In fact, traveling across the Atlantic was often a dangerous task that took months or years if you even survived. As a result, man has always been trying to find new ways to make this journey, faster, safer and more efficient. One example of this was the invention of steamships. These revolutionary vessels ruled the waves just a few centuries ago before becoming obsolete as man found even faster, safer and more efficient ways to travel, trade and fight wars. This, however, begs the question what happened to these transatlantic steamships which used to be the primary form of travel across this vast ocean?
