Castles conjure thoughts of romantic tales, but make no mistake, they are built for war.

Dover: Prince Louis' key to England. Malaga: the Granadans final stronghold. And Crac des Chevaliers: Crown Jewel of Crusader castles. Through dynamic location footage and immersive visual effects, Battle Castle reveals a bloody history of this epic medieval arms race.

As siege weapons and technology become more ruthless, the men who design and built these castles reply ... or perish. Follow host Dan Snow as he explores the military engineering behind these medieval megastructures and the legendary battles that became testaments to their might.

Each episode will climax in the ultimate test of the castle's military engineering -- a siege that will change the course of history. Which castles will be conquered and which will prevail? You'll have to watch to find out.

But the journey doesn't end there --in fact, it's just beginning. Battle Castle extends into a multi-platform quest, taking us deep into the secret world of medieval warfare and strategy. Become the ultimate 'Castle Master'. Stay tuned for more on the Battle Castle experience.
