"It's surprisingly simple.

Over the past 30 years Project for Public Spaces has evaluated more than 1,000 public spaces, and informally investigated tens of thousands more. From all this we have discovered that most great places--whether a grand downtown plaza or humble neighborhood park--share four key qualities:

1. It is accessible and well-connected to other important places in the area.
2. The space is comfortable and projects a good image.
3. People are drawn to participate in activities there.
4. It is a sociable place where people like to gather, visiting it again and again."
