Voting nearly doubled after the June results , when organizers said about 50 million votes had been cast . A single user can cast multiple votes . To be considered for the competition , all structures had to be built or discovered before 2000 . All are among top tourist attractions around the world . Of the seven ancient wonders of the world , only one remains standing today , the Pyramids of Giza in Egypt . Some nations have enthusiastically endorsed the new wonders campaign . Brazilian President Luiz Inacio Lula da Silva and Jordan 's Queen Rania actively promoted their countries ' hopefuls . But the new wonders campaign has n't been universally recognized . The United Nations ' cultural organization , UNESCO , issued a statement saying it has `` no link whatsoever '' to the vote . Egypt 's top antiquities expert also objected to the list . He said Egypt 's pyramids are a `` symbol of the genius of the ancient people '' -- and are above any sort of online poll . As a result , the organizers struck up a compromise . The pyramids have been assured honorary status , in addition to the new seven wonders . The new wonders project was the brainchild of Swiss businessman Bernard Weber . He said he wanted to invite the people of the world to take part in selecting the world 's greatest wonders . `` So that everybody can decide what the new seven wonders should be and not some government , not some individuals , not some institutions , '' he said . Vering said she believes the vote has accomplished that goal . `` We 've managed to bring culture out of the museum -- out of the dusty , dry academic corners -- and have people talk about it , '' she said . `` That , we feel , is the greatest achievement of this campaign .
