Located at the corner of S. Jackson Street and 4th Avenue S. in the Pioneer Square neighborhood, the station opened on May 20, 1911.[1] The Milwaukee Road discontinued passenger service to Union Station 50 years later, on May 22, 1961, and the Union Pacific followed suit on April 30, 1971. With no passenger rail service serving Seattle from Union Station, the building remained largely empty. An antique store filled the great hall for several years. After nearly 30 years of sitting idle, the station finally experienced an expansive renovation supported by Nitze-Stagen with financial backing from Microsoft co-founder Paul Allen. The Union Station's renovation was the winner of the 2000 National Historic Preservation Award.[2] The building has served as the headquarters of Sound Transit since 1999. Its grand hall is available to the public as a venue for weddings and other events.
In Seattle, the term Union Station refers not only to the main station building, but also to the
several adjacent office buildings at 505, 605, 625 and 705 5th Avenue South. Amazon.com was a major tenant of these properties from 2000[3] to 2011,[citation needed] all but one owned by Opus Northwest,[4] and the other by Vulcan.[5] The entire complex is earthquake-proofed by an underground ring of rubber.[6]
