Wikipedia says that "Porter Saloon was re-built" in 1925, a year after a fire destroyed it and much of the town. The Wikipedia article adds that "When it re-opened in 1933 following the repeal of Prohibition, it was one of the first establishments to receive a liquor license in the State of Washington," but contains no references. Thus with no primary references, my best guess from what I've found so far is that there was some kind of business built here in 1919, it burned down in 1924, and was rebuilt in 1925, it became a tavern in Dec. 1933, has been the Porter Saloon for many years, and in the last few years has had a quite remarkable remodel by Ms. Lee.
Est. 1933? - Building constructed: 1925
