One of the more unique, local landmarks in Seattle is the Fremont Troll. Trolls are originally from Scandinavian folklore, and while they have been characterized as possessing a number of undesirable traits, you can pretty much sum it up as ugly outcasts that live in dark places, like under bridges. This sculpture seems to fit the bill.
Created after a contest held by the Fremont Arts Council to do something beneficial with the space under the Aurora bridge, the troll was made in 7 weeks out of rebar steel, wire, and 2 tons of ferroconcrete. It's quite climbable, if that's your thing. Spending a short period of time there, there did seem to be a steady trickle of tourists eager to get a photo with the troll, myself included.
