Wall a town to keep out the wind?

Mad science/weather physicsfilter: I live in a small town in the Midwest right at the moment. It gets very, very cold, and most of the actual suffering part of the cold is due to high winter winds. Why can't towns like this just build city walls, ancient Athens-style, say 20 feet high or so (more?) to keep the wind out? There must be some obvious physics/ecology reason why this wouldn't work, someone explain it to me?
