This book is about what people at different moments in history and in different cultures thought defined a city and how these ideas changed over time.

It contains many pictures, including drawings and graphic art, some dating from as far back as the Middle Ages, but also illustrations from science fiction books and pictures from movies, as well as drawings I myself and my friend the architect Sam Chermayeff made. There are also maps of cities that children invented. As with the other books in the series, there’s a lot of room for you to draw in and put your dreams and fantasies on paper. You can start right away, building the city in which you’d love to live.
