David Macaulay: Castle (1983)

David Macaulay, the illustrator behind the picture book Castle, visits real Welsh castles with co-host Sarah Bullen, while animated sequences show his imagined castle rising stone by stone. It dates from 1983 and looks it, but children who like building things tend to forget that once the drawings start moving. Macaulay wanted viewers to understand the castle as a weapon of war, so the story also covers the people who attack it. That makes it a natural next step for kids who have spent an afternoon designing their own fortress.
