Castle

I'm still figuring out if this is a children's book or not but either way it's an amazing book with a lot of illustrations of Château-Gaillard and its siege!!
The siege is very well explained, has a lot of details about it and even explains various fun facts about how sieges worked.
The book is very interactive, having unfoldable pages and little books (the Diary of Roger de Lancy) telling how the history of Gaillard happens.
Another book that helped me a lot in my video about the history of this French/English castle
