In Cathedral, David Macaulay walks kids (and adults) through how a cathedral was constructed, using the fictional French Gothic cathedral to do so. Each page has lavish pen-and-ink drawings (example below) illustrating the text.
This is a wonderful book. Meant for kids but useful, informative, and enjoyable for all, I may get this to add to our home library. Not only is Macualay's art impressive, but he helps convey the complexity and challenge of cathedral construction (and associated realities, like stoppages in construction and death of participants, since they took generations to build) in simple terms. Highly recommended.
