London Bridge was falling down, so it got relocated to Lake Havasu City, Ariz. No, really. It is the very London Bridge built in 1831 that once sat astride the Thames across the pond. But by the mid-20th century, it could no longer handle the load of London's traffic and got auctioned off to an Arizona oil baron — he spent $2,460,000 on the bridge and then an extra $7 million to have it dismantled and reconstructed in Lake Havasu City in 1971. Guinness World Records calls it the world's largest antique. So you can drive over or stroll along a 950-ft.-long piece of history, complete with a Tudor backdrop. It's like being in two places at once.
