Well, I must say I don't agree with the final winners
If it were up to me, these are the final seven monuments (in no particular order) I'd have chosen to represent humanity!
1. Eiffel Tower (Paris, France)
2. Colosseum (Rome, Italy)
3. Statue of Libery (New York, USA)
4. Acropolis (Athens, Greece)
5. Opera House (Sydney, Australia)
6. Sagrada Familia (Barcelona, Spain)
7. Neuschwanstein (Fussen, Germany)
However, I'm not that convinced that adding the Colosseum and the Acropolis is entirely fair, since they are both ancient buildings. In this case, if I was forced to change them, I'd choose Versailles, the Tower of Pisa or the Louvre.
I'd be really interested to know what are your Wonders
