Bridges look simple, but they quietly reshape the world around them. From Tolkien’s Last Bridge to the rainbow span of Bifröst, bridges in fantasy turn geography into decisions, create natural chokepoints, and mark the crossing from one world into another. As history shows—from Roman Corbridge to the Rhine in 1945—who controls the bridge often controls the story. Which may be why so many unforgettable fantasy moments happen right in the middle of one.
