Medieval Fortification

In this episode, we explore the world of medieval fortification and how defensive architecture evolved across Europe after the fall of the Roman Empire. Focusing on key structures such as motte-and-bailey castles, fortified harbors, and defensive religious buildings, we examine the strategic features that helped repel invaders, including towering stone keeps, thick curtain walls, moats, arrow loops, and carefully designed killing fields. The discussion also highlights how advancements in siege warfare—particularly the use of heavy catapults—shaped the design of these fortifications. Finally, we look at how the introduction of gunpowder and cannons transformed warfare, ultimately making traditional stone defenses obsolete and paving the way for new approaches to military architecture.
