This is Portland's most famous vacant building, the office and admin building for Portland Gas & Coke, the forerunner to NW Natural Gas. Since 1957 it's just sat here, vacant, ever since, but last month the gas company says it costs too much to maintain even the way it is, it so they're tearing it down.
Which is a shame, it's a beautiful Gothic Victorian built around 1912 or so.
It's hard to get a good view for photography, the public isn't allowed to get near it. It's surrounded by private roads and gas tanks and other heavy industry operations, plus the whole area is a Superfund site. I went there at 1:30 pm and it was already in shadows, I had to do some post processing to get a reasonable view of it.
Most pictures turned out dark like this
