Time travel is one of those ideas that remains popular. The thought of stepping back into the past, not just reading about it, but actually being there, in the places and events you’ve only ever seen in history books, to witness a moment as it happened, to see familiar names as real people, or simply to stand in a place before everything changed.

What would you choose? A famous event? A quiet moment that history barely remembers? The appeal isn’t always in changing anything — often, it’s just in seeing it for yourself.

In books and in film, time travel allows us to visit the past or imagine the future.
