Revising our cities changes the way we think of places, and the way we think of ourselves as belonging. Sometimes, these changes substantially alter the image that citizens have of their home places. And occasionally, as in Millennium Park in Chicago, these changed perceptions can be very big, and very good.
Sometimes individual buildings in the private realm can have a major positive affect on how we think of places. But most often, changes to the public realm are the changes we feel the most.
