Children's LiteratureCompleted in 1996, the graceful Petronas Towers in Kuala Lumpur, Malaysia, were the two tallest building in the world. Through a worldwide competition, an American architecture firm was chosen to design two towers to be an expression of Malaysian culture. To minimize their cost and their swaying in the wind, the towers were constructed of concrete. From the creative foundation of the towers, to the unique stainless steel and glass exterior, to the sky bridge connecting the towers at the 41st and 42nd floors, there were many innovations in the striking design. Besides offices and stores, the towers house a concert hall, science museum, and cinema. The builders had to find ways to do daily maintenance, such as a system to wash windows from each level of the tall buildings. It takes a month for crews to wash all of the windows from a carrier suspended from a mechanical arm extended from the building. This book is an excellent resource for the school library. A list of other books and websites is included in the back of the book. The Petronas Towers is part of the "Building World Landmarks" series. 2004, Blackbirch Press/The Gale Group/Thomson Learning, Ages 7 to 14.
