The Economics of Owning a Medieval Fortress | Simon's View

Hey, Simon here! What did it actually cost to own one of the most important fortresses in medieval England? At first, Dover Castle looks like a terrible investment. Henry II spent more than £6,000 transforming it into a major royal fortress, and after that the money still kept disappearing into soldiers, food, repairs, weapons, carpenters, stores and maintenance. The walls do not grow grain. The towers do not collect rent. And in a peaceful year, the entire place mostly seems to sit on a cliff and consume money. So why spend a fortune on it? That question only started making sense to me when I looked at the siege of 1216, when Prince Louis of France invaded England and one fortress suddenly forced a much larger army to stop, build siege engines, dig mines, consume supplies and spend months trying to remove a single problem from the map. In this video, I’m looking at Dover Castle, garrison costs, castle-guard service, medieval military finance, siege logistics, repairs, strategic geography, and why a fortress sitting beside the right road, port or crossing could be worth far more than the land underneath it. Because maybe the economics of a fortress were never really about how much money the walls could make. They were about how much they could stop you from losing. And once I started looking at Dover that way, the most valuable thing inside the castle was no longer the stone. It was time.
