Lena: Have you ever walked across London Bridge, Miles? I mean the actual London Bridge, not Tower Bridge that tourists often confuse it with.
Miles: I have! And it's fascinating because the London Bridge we walk across today is actually the third major version. The original stone bridge from medieval times was an architectural marvel of its day.
Lena: Wait, so there have been multiple London Bridges? I had no idea!
Miles: Oh absolutely. The first stone bridge was started in 1176 and took 33 years to build. Before that, there were wooden bridges dating back to Roman times. But the medieval stone bridge was something special—it had houses and shops built right on it, like a street suspended over the Thames.
Lena: That sounds incredible! I'm picturing this bustling little neighborhood right on the bridge. How long did that version last?
Miles: It stood for over 600 years! Can you believe it? Though it went through many repairs and modifications. The houses made it incredibly narrow—only about 4 meters for traffic in some places. Crossing it could take an hour with all the congestion.
Lena: Wow, and I thought modern London traffic was bad! So what happened to that original bridge with all the houses?
Miles: It was eventually replaced in the 1830s with a wider stone bridge designed by John Rennie. But here's where the story gets really interesting—that second London Bridge was actually sold to an American businessman in 1968 and rebuilt brick by brick in Arizona!
Lena: No way! London Bridge is in Arizona? That sounds like the start of a joke!
Miles: It's absolutely true! Let's explore how this iconic piece of London history ended up in the Arizona desert, and the fascinating story behind all three versions of this historic crossing.
