London, England: St. Paul's Cathedral

Think big.

St. Paul's Cathedral in London certainly qualifies. It's the biggest church in England at 515 feet and 250 feet wide, and is the fourth largest church in Europe. (It looks like the other three are in Italy.)

The site has hosted a church of some sort since 604, but the current place was built after a fire in 1666. For Britain, this has become a symbol of resistance. When Germany was bombing London during World War II, volunteers manned the hoses to make sure that the structure didn't go completely up in flames.

Want history? This is where Prince Charles married Lady Diana Spencer in 1981. Horatio Nelson is entombed here, and so is the Duke of Wellington. Churchill and Thatcher had funerals here.

And if you want views, climb 528 steps to the top of the dome. If you want fun, climb 257 steps to the Whispering Gallery.

Now, about the photo. I took a standard shot of the place from the outside, which was fine. But then I went into a shopping center across the street to use the facilities. When I started to walk out toward the street, the view simply jumped out at me. It's a unique look at the Cathedral.
