London Bridge

London is one of the most famous European cities. When you hear London, you'll automatically begin to sing the nursery rhyme, London bridge is falling down..., well, a lot of times, I do that, I just don't know about you. Anyway, the London bridge is actually very historic and significant. It's a bridge over the River Thames. There was an old one, which fell when the Romans left and it was actually repaired many times, until the new one was built, and replaced the old one.
