An unusual adaptive reuse journey in Portland–from car dealership to bank offices to local government–was nearly capped off with an impressively bonkers bit of public art, a "green roof sculpture” with a 50-foot windmill, earthen mounds, and a tree atop a rotating platform.

The Portland Public Market lasted less than a decade as a market and within 40 years the whole thing was torn down–this building was a boondoggle. An illuminating boondoggle, though.
