The Little Mermaid

There's nothing that says "I've been there" better than standing with 50 other tourists trying to capture the perfect shot of an iconic statue that's been photographed thousands of times a day, every day of the year, for the past several decades. The Little Mermaid--the graceful statue sculpted by Edvard Eriksen and unveiled at Copenhagen's Langelinie wharf exactly 96 years ago tomorrow--has, alas, suffered physical abuse as silently as her prose counterpart. Having been decapitated twice, she now has a neck filled with concrete to keep evil-doers at bay (and precluding the need for a "Forurening forbudt" plaque, which would detract from the photographs).

You know you've found all the right tourist spots when you start recognizing the other visitors.
