Zooming through time 56 years, we have a circa-2016 physical layout of the historic GREENHILLS CENTER complex. Of all three green town centers, it is in the worst state of repair. The good news is that a great deal of the facility is structurally original. 

We end our GREENHILLS CENTER write up with a contemporary view of the shopping hub. Whereas Greenbelt {in Maryland} and Greendale {in Wisconsin} have developed much of the original greenbelt forests that surrounded them, the city of Greenhills has not grown appreciably, leaving much of its greenbelt area intact.
