Squares don’t create activity — activity creates squares. In other words, “People do not use city parks and squares because they are parks and squares, but because of the uses to which adjoining streets put them.” -The Death and Life of Great American Cities by Jane Jacobs

I love this book, and it is used in many Urban Planning courses. She notes that Rockefeller Plaza works because it borrows life from the city. It is surrounded by offices, shops, restaurants, transit and used all day by different groups (workers, tourists, skaters, diners). Rockefeller Plaza succeeds because it is intensely connected to daily life and fed by continuous pedestrian traffic.
