The Large Hadron Collider and the International Space Stations are amazing wonders. It used to be that humanity's most expensive projects were religious temples. Now it's machines for scientific research. Some people apparently have a problem with this, and they're generally not the sort of people I like to be around.
The duomo took 600 years to be mostly complete and still has work being done though mostly restoration and maintenance. It has a marble quarry dedicated solely to it. Absolutely magnificent building, I did all the tours a few months ago, loved it.
That is why we don’t build buildings like it anymore, insanely expensive and time consuming. Plus our current rich people would rather rape kids on their massive yachts and private island than commission beauty to be admired by wider society like the wealthy of old.
Idk if this is truly a wonder, but when I heard about it earlier this year I was stunned by how magnificent it looked. NJ opened the largest Hindu temple outside of Asia last fall. It looks crazy.
In late game, Wonders are for culture and not science victories. We need to put more into one and get the other, as Canada just stole Einstein from me.
I realize it's a joke but answering to the first tweet - one could simply post a picture of the Sagrada Familia which is super impressive if you've seen it live and it's still under construction today.
CopenHill deserves a mention, although it would be nice if it were more of a blueprint for industrial architecture going forward, rather than a wonder unique to one progressive European country.
I can't think of a single thing built in the last century that will still be there in a thousand years. We may still build some cool stuff, but none of it is durable anymore it seems.
