I know that this is a (very funny) joke, but when I visited Rome I was absolutely astonished that humans could build something so long ago and still stand today. Most people don't have such a visible (obvious), lasting impact on the physical world.

Joking aside, Rome does have some amazing old architecture. The Pantheon's dome ceiling is remarkable and that's just one example.

I don't think Germany can claim buildings superiority either given the lack of skyscrapers

The Berlin TV Tower is fairly tall
