I think of time travel as a very London concept. I’ll explain why.
Living in London means that you constantly come across the past. The Tower of London is the most obvious example: it’s surrounded by buildings from all sorts of different periods, but never looks out of place. And then there are the more subtle details: faded advertisements painted on the sides of buildings, abandoned tube stops, even coal-hole covers set into the pavement.
If you look at this city from the right angles, you can transport yourself – albeit briefly – into the past.
Time travellers might wish to investigate further: here and here.
