If anything can capture a moment or a memory better than our brain, it's a photograph. And sooner or later we are bound to become a memory too. Photos can keep things alive in a very different way. Also, you can't possibly remember every moment of your life but photos help. Same is the case with the world.

Here 40 such unique photos through history that you may not have seen before:
