The Seattle Underground is a network of underground passageways and basements in the Pioneer Square neighborhood of Seattle, Washington, United States. They were located at ground level when the city was built in the mid-19th century but fell into disuse after the streets were elevated. In recent decades, they have become a tourist attraction, with guided tours taking place around the area.
After the Great Seattle Fire of June 6, 1889, [1] [2] new construction was required to be of masonry, and the town's streets were regraded one to two stories higher. Pioneer Square had originally been built mostly on filled-in tidelands and often flooded. The new street level also kept sewers draining into Elliott Bay from backing up at high tide.
For the regrade, the streets were lined with concrete walls that formed narrow alleyways between the walls and the buildings on both sides of the street, with a wide "alley" where the street was. The naturally steep hillsides were used and, through a series of sluices, material was washed into the wide "alleys", by raising the streets to the desired new level, generally 12 feet (3.7 m) higher than before, in some places nearly 30 feet (9.1 m).
At first, pedestrians climbed ladders to go between street level and the sidewalks in front of the building entrances. Brick archways were constructed next to the road surface, above the submerged sidewalks. Vault lights (a form of walk-on skylight with small panes of clear glass which later became amethyst-colored) were installed over the gap from the raised street and the building, creating the area now called the Seattle Underground.
When they reconstructed their buildings, merchants and landlords knew that the ground floor would eventually be underground and the next floor up would be the new ground floor, so there is very little decoration on the doors and windows of the original ground floor, but extensive decoration on the new ground floor.
Once the new sidewalks were complete, building owners moved their businesses to the new ground floor, although merchants carried on business in the lowest floors of buildings that survived the fire, and pedestrians continued to use the underground sidewalks lit by the vault lights (still seen on some streets) embedded in the grade-level sidewalk above.
In 1907, the city condemned the Underground for fear of bubonic plague, two years before the 1909 World Fair in Seattle (Alaska-Yukon-Pacific Exposition). The basements were left to deteriorate or were used as storage. Some became illegal flophouses for the homeless, gambling halls, speakeasies, and opium dens.[ citation needed ]
Only a small portion of the Seattle Underground has been restored and made safe and accessible to the public on guided tours. In 1965, local citizen Bill Speidel formally created "Bill Speidel's Underground Tour", which continues to operate from the Pioneer Building and adjacent buildings. [3] The tour route passes disused storefronts, artifacts, and multiple tunnel entrances.[ citation needed ] [4]
A second tour, Beneath the Streets, was created in 2013 and uses other sections of the Underground network. [5]
A skyway, skybridge, skywalk, or sky walkway is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. Urban skyways very often take the form of enclosed or covered footbridges that protect pedestrians from the weather. Open-top modern skyways in mountains now often have glass bottoms. Sometimes enclosed urban skywalks are made almost totally from glass, including ceilings, walls and floors. Also, some urban skyways function strictly as linear parks designed for walking.
Pioneer Square is a neighborhood in the southwest corner of Downtown Seattle, Washington, US. It was once the heart of the city: Seattle's founders settled there in 1852, following a brief six-month settlement at Alki Point on the far side of Elliott Bay. The early structures in the neighborhood were mostly wooden, and nearly all burned in the Great Seattle Fire of 1889. By the end of 1890, dozens of brick and stone buildings had been erected in their stead; to this day, the architectural character of the neighborhood derives from these late 19th century buildings, mostly examples of Richardsonian Romanesque.
An underground city is a series of linked subterranean spaces that may provide a defensive refuge; a place for living, working or shopping; a transit system; mausolea; wine or storage cellars; cisterns or drainage channels; or several of these. Underground cities may be currently active modern creations or they may be historic including ancient sites, some of which may be all or partially open to the public.
David Swinson "Doc" Maynard was an American pioneer, doctor, and businessman. He was one of Seattle's primary founders. He was an effective civic booster and, compared to other white settlers, a relative advocate of Native American rights. His friendship with Chief Seattle was important in the formation of the city of Seattle, and it was he who proposed the city be named for this important chief. Maynard was Seattle's first doctor, merchant prince, second lawyer, Sub-Indian Agent, Justice of the Peace, and architect of the Point Elliott Treaty of 1855.
The street layout of Seattle is based on a series of disjointed rectangular street grids. Most of Seattle and King County use a single street grid, oriented on true north. Near the center of the city, various land claims were platted in the 19th century with differently oriented grids, which still survive today. Distinctly oriented grids also exist in some cities annexed by Seattle in the early 20th century, such as Ballard and Georgetown. A small number of streets and roads are exceptions to the grid pattern.

Path is a network of underground pedestrian tunnels, elevated walkways, and at-grade walkways connecting the office towers of Downtown Toronto, Ontario, Canada. It connects more than 70 buildings via 30 kilometres (19 mi) of tunnels, walkways, and shopping areas. According to Guinness World Records, Path is the largest underground shopping complex in the world, with 371,600 square metres (4,000,000 sq ft) of retail space which includes over 1,200 retail fronts (2016). As of 2016, over 200,000 residents and workers use the Path system daily with the number of private dwellings within walking distance at 30,115.
The Rayburn House Office Building (RHOB) is a congressional office building for the U.S. House of Representatives in the Capitol Hill neighborhood of Washington, D.C., between South Capitol Street and First Street.
A utility vault is an underground room providing access to subterranean public utility equipment, such as valves for water or natural gas pipes, or switchgear for electrical or telecommunications equipment. A vault is often accessible directly from a street, sidewalk or other outdoor space, thereby distinct from a basement of a building.
William C Speidel (1912–1988) was a columnist for The Seattle Times and a self-made historian who wrote the books Sons of the Profits and Doc Maynard, The Man Who Invented Seattle about the people who settled and built Seattle, Washington.
Lou Graham, born Dorothea Georgine Emile Ohben, was a German-born woman who became famous as the madame of a brothel in what is now the Pioneer Square district of Seattle, Washington, United States. She was referred to as the "Queen of the lava beds," with 'lava beds' referring to the area of tide flats that were filled in with sawdust from the sawmill. She became one of the city's wealthiest citizens before dying in her forties.
Henry Leiter Yesler was an American entrepreneur and a politician, regarded as a founder of the city of Seattle. Yesler served two non-consecutive terms as Mayor of Seattle, and was the city's wealthiest resident during his lifetime.
The Pioneer Building is a Richardsonian Romanesque stone, red brick, terra cotta, and cast iron building located on the northeast corner of First Avenue and James Street, in Seattle's Pioneer Square District. Completed in 1892, the Pioneer Building was designed by architect Elmer Fisher, who designed several of the historic district's new buildings following the Great Seattle Fire of 1889.
The Stockton Street Tunnel is a tunnel in San Francisco, California, which carries its namesake street underneath a section of Nob Hill near Chinatown for about three blocks. It was opened in 1914. The south portal is located just shy of Bush Street, which is about two blocks to the north of Union Square. The north portal is located just to the south of the Sacramento Street intersection.
Westlake station is a light rail station that is part of the Downtown Seattle Transit Tunnel in Seattle, Washington, United States. The station is located under Pine Street between 3rd and 6th avenues in Downtown Seattle, near Westlake Center and Westlake Park. It is served by the 1 Line, part of Sound Transit's Link light rail system, and also connected above ground by buses at several stops, the South Lake Union Streetcar, and the Seattle Center Monorail.
The Prentis Building and DeRoy Auditorium Complex consists of two educational buildings, the Meyer and Anna Prentis Building and the Helen L. DeRoy Auditorium, located respectively at 5201 and 5203 Cass Avenue in Midtown Detroit, Michigan, on the campus of Wayne State University. The buildings were built at the same time, and were designed by architect Minoru Yamasaki to interrelate functionally, spatially, and architecturally. The buildings were constructed at a critical point in Yamasaki's career when he was experimenting with ornamentation, light and shadow, and the use of pools and gardens to soften perception of standard International Style architecture. The complex was listed on the National Register of Historic Places in 2011.
The Lyon Building is a historic building located at 607 Third Avenue in Downtown Seattle, Washington, United States. It was built in 1910 by the Yukon Investment Company and was named after the city in France of the same name, reflecting the French heritage of the company's owners. It was designed by the firm of Graham & Myers in the Chicago school style of architecture and was built by the Stone & Webster engineering firm, whose use of non-union labor would make the yet unfinished building the target of a bombing by notorious union activist James B. McNamara, who would commit the deadly Los Angeles Times bombing only 1 month after. The Lyon Building was luckily not destroyed due to its substantial construction, and after little delay, it was completed in 1911 and soon became one of Seattle's most popular office addresses for lawyers and judges due to its proximity to Seattle's public safety complex and the King County Courthouse. It was the founding location of many foreign consuls, social and political clubs as well as the City University of Seattle. The building's basement now serves as an entrance the Pioneer Square station of the Seattle Transit Tunnel. The Lyon Building was added to the National Register of Historic Places on June 30, 1995 and was designated a Seattle landmark on August 16, 1996. In 1997 it was converted to residential use as a shelter and services center for the homeless and at-risk by the non-profit Downtown Emergency Service Center, who are the current owners of the building.
Vaulted sidewalks are sidewalks that are not placed directly on the ground. Rather, there is an empty space below them where the ground level used to be. This happens in cities where the street level has been raised over time.
Pavement lights (UK), vault lights (US), floor lights, or sidewalk prisms are flat-topped walk-on skylights, usually set into pavement (sidewalks) or floors to let sunlight into the space below. They often use anidolic lighting prisms to throw the light sideways under the building. They were developed in the 19th century, but declined in popularity with the advent of cheap electric lighting in the early 20th. Older cities and smaller centers around the world have, or once had, pavement lights. In the early 21st century, such lights are approximately a century old, although lights are being installed in some new construction.
The Mutual Life Building, originally known as the Yesler Building, is an historic office building located in Seattle's Pioneer Square neighborhood that anchors the West side of the square. The building sits on one of the most historic sites in the city; the original location of Henry Yesler's cookhouse that served his sawmill in the early 1850s and was one of Seattle's first community gathering spaces. It was also the site of the first sermon delivered and first lawsuit tried in King County. By the late 1880s Yesler had replaced the old shanties with several substantial brick buildings including the grand Yesler-Leary Building, which would all be destroyed by the Great Seattle Fire in 1889. The realignment of First Avenue to reconcile Seattle's clashing street grids immediately after the fire would split Yesler's corner into two pieces; the severed eastern corner would become part of Pioneer Square park, and on the western lot Yesler would begin construction of his eponymous block in 1890 to house the First National Bank, which had previously been located in the Yesler-Leary Building. Portland brewer Louis Feurer began construction of a conjoined building to the west of Yesler's at the same time. Progress of both would be stunted and the original plans of architect Elmer H. Fisher were dropped by the time construction resumed in 1892. It would take 4 phases and 4 different architects before the building reached its final form in 1905. The Mutual Life Insurance Company of New York only owned the building from 1896 to 1909, but it would retain their name even after the company moved out in 1916.
