This massive excavation was a three-story sub-basement for the Pittock Block, which originally housed the Northwestern Electric Company’s electric sub-station and west side distribution plant. Portland newspaper publisher Henry Pittock’s home was on this site before construction began. This view looks down on the corner of SW 10th and Washington, facing northeast. I’d featured a cropped version of this image previously; VP fan Mike Slama was kind enough to point me to this full version.
The Columbia Building once stood on the northeast corner of SW Washington Street and 9th Avenue. This photo looks east, and construction in the foreground is the Pittock Block across SW 9th Street to the west. According to the University of Oregon Libraries; “The Columbia Building was originally five stories and an additional two stories were added soon after construction. The building was demolished in 1972 to make way for O’Bryant Square which now occupies the site. Columbia Building was built for E. J. Blazier who operated Blazier Brothers Saloon, Burnside Street.”
