you were looking to buy flapjack flour in bulk, this here was the place. At one point, the Albers Brothers were the largest grain and cereal manufacturing company this side of, well, Nevada. This brick building is the oldest feed mill still in Portland (it contained a dog food factory at one time), and it's enjoyable for the painted artwork on the silos, which are nicely visible from the Broadway Bridge.
* During World War I, J. Henry Albers (president of the milling company) was arrested on suspicion of treason for drunkenly singing in German on a train ride from San Francisco. Sentenced to three years in jail, he successfully appealed, but found himself ruined; he was expelled from his Elks Lodge and died shortly thereafter.
This old building was near death before it went through a dramatic renovation and conversion to waterfront office space in 1989. In a precursor to the sustainability designs that became de rigueur a decade later, the old mill has a heat exchanger that pumps water from the Willamette into the building, keeping it warm when it's cold and cool when it's hot. In order to get on the National Register of Historic Places, its old bricks had to be hand scrubbed (as opposed to steam cleaned).
