Another suggestion:
The Bahai Gardens
The Bahai Gardens
Etemenanki looks different enough from the Ziggurat improvement, same goes for the cathedral wonders and the Cathedral faith building. Pont du Gard doesn't look much different from the in-game Aqueducts. I'm also more impressed by the Segovia aqueduct than Pont du Gard. It would look weird as a wonder in-game, that one famous section of aqueduct with nothing connecting it.....If the Pont du Gard is left out for being an Aquaeduct, why would you include a wonder like Etemenaki or cathedral wonders?
I'll consider it the Smithsonian Institution Building. National Mall is too big and has so many buildings.I'd be cautious about adding things such as the Smithsonian Institution, considering it accounts for a number of sites and museums in the USA, none of which individually I would call Wonder-worthy. Perhaps the Smithsonian Institution Building more specifically? Or the National Mall which encompasses most of the museums as well as other notable monuments?
Bridges should not be included.
If bridges aren't included, I'm not really sure why dams should be either. Again, they're not really something you can do in Civ VI.
Let's act that some rivers would get the "Nile treatment" from the Nubia and Egypt scenario. Then it would be no problem to add bridgesPerhaps they can be built next to a lake?
I'm not really motivated to remove the dams from the list. I actually would like to see bridge wonders. Too bad rivers are just lines between hexes.
Suggestion: Hwangnyongsa Temple (Korea). No longer survives (except its massive foundations), but at the time the Dragon Temple was finished, it was the center of Korean Buddhism, and the largest wooden structure in the world at the time of its completion by Queen Seondeok.
I agree with opinions above stating that bridge wonders shouldn't be a thing. We have plenty of impressive structures (palaces, temples, etc) without having to resort to elevating bridges (or roads) to world wonder status. Also, having been to the Pont du Gard, I think it was impressive but hardly a world wonder.
So what would the bonuses be? Would they all require bodies of water? Do people pay money to visit the bridges? There are few iconic bridges and of them, very few if any could be said to be world wonders.Bridges are iconic. See Kimiimaro's list. Those are all major tourist attractions.
