But its strength wasn’t just geography—it was engineering.This video explores how builders turned a volcanic peak into Scotland’s most important stronghold: How sheer cliffs eliminated the need for defenses on three sidesHow walls, gates, and towers were concentrated along the only accessible route How materials were hauled up steep slopes to construct massive stone fortifications How the castle was expanded and reinforced over centuries of warfare Using AI-generated historical reconstructions, the film visualizes how the fortress grew from early medieval defenses into a powerful royal and military center dominating the landscape.Edinburgh Castle wasn’t just built on a volcano.
