I was reminded recently of a Portland oddness when I had to go to a house there--
Ladd's Addition. If you zoom out you'll see that the place is drastically odd in relation to Portland's overall grid system, and I swear there's a space warp in there because even people who made a living from being able to find anything (like me, for instance) get turned around and lost in that place--even the residents do, too! It's a beautiful neighborhood, though, check it on street view.
We also have a large, tacky
Paul Bunyan statue.
ETA: Washington has a
Stonehenge too, in Maryhill on the Columbia Gorge. It's cool and is even oriented correctly so it works the way the original one does. It's also a WWI memorial.
