These books provide guided tours through several eras of architecture, offering cultural context as well as clear discussions of the building process. Pyramid focuses on the making of Pharaoh Khufu's tomb while also providing an overview of how ancient Egyptians treated their dead, where the soul was believed to go, and how archaeologists have uncovered information about the civilization. The other titles are more general, describing the construction of similar cities, houses, theaters, and castles rather than focusing on a single example. There is no direct flow to the narratives; instead, each spread covers a topic, and students follow text boxes around the cartoonlike illustrations to learn about individual steps of the construction process, the culture, or the archaeology involved. The illustrations feature figures who sometimes explain their roles using funny comments that appear in speech balloons. Each book's time line includes recent discoveries.
