Portland spreads out below Piggot’s Castle in this nice 1907 bird’s eye view. The 1892 castle still sits on SW Buckingham Drive and is visible up the hill from the foot of SW Broadway looking south. Broadway is seen here on the left.
The Chamber of Commerce building occupied the half block on the north side of SW Stark between SW 3rd and 4th Avenues. You can see it nearing completion in 1892 in this Portland panorama of the same year; it’s just to the left of center with all the derricks on its roof. Economic difficulties, taxes and maintenance dictated its demolition in 1934. The site remains a surface parking lot to this day.
