What’s inside a skyscraper? Who directs traffic? Where is the electricity that lights up the streets at night from? What does the inside of a fire station look like? Why are different neighborhoods made up of different kinds of buildings? From lift-up flaps to pop-up pages, 55 interactive elements bring the city to life! Readers will learn all about cities and how they work, their spaces and infrastructure, what goes on behind the walls of buildings and under the pavement, how cities are cleaned… Each two-page spread has its own theme: traffic, the business district, underground, parks, big department stores, security and emergency services, residential neighborhoods, how cities can change.
