11-Story City Hall Building in Downtown Chicago

11-Story City Hall Building in Downtown Chicago
This beautiful rooftop garden brings a touch of nature to the top of the 11-story City Hall building in downtown Chicago. Placed directly amid the noisy chaos of urban life, the functioning garden is the most famous in all of the city.

To describe the success of the project, the website explains, "The City Hall Rooftop Garden absorbs less heat from the sun than the [original] tar roof, keeping City Hall cooler in summer and requiring less energy for air conditioning. The garden also absorbs and uses rain water. It can retain 75% of a 1 inch rainfall before there is stormwater runoff into the sewers."
