The Triangle Hotel was opened for use late in 1910, replete with saloon and eight rooms. The building continued to be operated under that name until 1945. Owing in large part to its accessibility from the docks and railroads, it had eventually become a brothel. The ground story was maintained as a neighborhood tavern known as the Triangle Bar until 1929, at which time the Western Union Telegraph Company located its "C" Branch office in the space. The first branch location to serve the main office of Western Union in Seattle, "C" Branch is believed to have been one of the early urban branch offices established by the telegraph company. Communiciation [sic] with the head office in Seattle at Second Avenue and Cherry Street was conducted via pneumatic tubing. Upon Western Union's departure from the premises in 1954, the ground story was re-outfitted for tavern use, a function which has only recently been phased out.

3. Triangle Hotel and Bar Marker
The latest incarnation of the tavern, called Seattle's Historic Triangle Pub, was a popular pregame spot for Seahawks and Mariners fans. According to a Facebook post by Vanishing Seattle, it closed permanently in June 2020 after 22 years in business as a result of the COVID pandemic, frequent road closures stemming from nearby construction, a broken sewer pipe and failed lease negotiations with a new landlord. The landlord has indicated plans to turn the building into a boutique hotel.
