Greatest tourist attractions made by man

These sights are old, older, and ancient. But I just couldn't include newer attractions like Taj Mahal, Statue of Liberty, or the Eiffel Tower, impressive as they are. I guess what they need is some patina.

5. Ancient Rome

Colosseum, Pantheon, Forum Romanum... the centre of Rome is like a big outdoor museum, full of incredible sights. And don't forget all the small details, like lampposts, faucets and door knobs!

4. Pyramids of Giza

Well, after all these are the only remaining monuments of the original seven wonders.

3. The Great Wall of China

I can't wait to go to the moon and find out if the Great Wall is really visible from there!

2. City of Angkor

You can spend a whole day here, going from monument to monument. It's a great adventure.

1. Machu Picchu, Peru

It's not so much the buildings themselves than the surroundings. The location is 2430 meters above sea level, hidden between the magnificient Andies.
