If you want a deeper analysis of the castles and sieges featured in Battle Castles there is an amazing book to accompany the series, written by Dan Snow and published by Harper Collins.
You can read the Introduction: The Rise and Fall of the Medieval Castle
In the book Dan delves even deeper into the castles from the series: from Dover Castle to Château Gaillard, Richard I’s fortress in Normandy, and Castillo de Gibalfaro, the last vanguard of Moorish rule in Spain, to Krak des Chevaliers in Syria – an astounding feat of engineering by the Crusaders.
Each castle’s story is dramatically recounted: the building techniques, the weapons used and daily life within the walls. Spanning the globe, and using the latest CGI reconstructions, Dan Snow gets to the very heart of the bloodshed and battles of the greatest fortresses of the Middle Ages.
