And the winners are:
Chichen Itza, Mexico
Christ Redeemer, Brazil

The Great Wall, China
Machu Pichu, Peru
Petra, Jordan
The Roman Colloseum, Italy
The Taj Mahal, India
There was global voting to decide the winners. In fact, there is a website that describes these wonders and all the runners up. It was announced on 7.07.07 in Lisbon, Portugal. More than 100 million votes were cast for the winners.
How do the new 7 wonders compare to the old? Here’s they’re list:
The Original Seven Wonders of the World (AKA the 7 Wonders of the Ancient World):
The Great Pyramid of Giza
The Hanging Gardens of Babylon
The Statue of Zeus at Olympia
The Temple of Artemis at Ephesus
The Lighthouse (Pharos) of Alexandria
The Mausoleum at Halicarnassus
The Colossus of Rhodes
I found some good info about these and their origin on ABC.com.
