建在悬崖上的城市为我们展示了自然世界和人类之间的挑战、征服、壮观的鲜明对比，通过这样矗立在悬崖边上的城市来了解人类的伟大和自然界的壮观。

许多古老的城市由于各种不同的原因，有的是为了防御、有的是为了统治，而建立在先对危险的环境，站立在这样的城市之巅俯瞰远方，你怎么看？

Cities built on cliffs present us with a striking contrast between the natural world and the structures that we build to challenge and overcome it. These photos capture stunning views of some of the most epic cliff-side cities in the world.

Many cities or dwellings could have been built on cliffs for a variety of different reasons, but this was most often done with defensive advantages in mind. A cliff-side city overlooking a sea passage has a superior command of the surrounding waters and is virtually impossible to assault from the water.

Cities on steep hills, on the other hand, might have been built there to defend from land-based aggressors or because of their proximity to important landmarks like rivers.If you've ever traveled to a cliff-side city with stunning views, we'd love to see them!
