When I went to Athens and saw the Parthenon, I wondered why they didn't restore the Parthenon to it's original state, sort of how Notre Dame is being restored after the fire.
Well, I just found that the Parthenon has been recreated in a couple of places, one of which is Nashville, TN! It's an exact reproduction of the original in Athens.

There's a second one that may not be exact but is close, located in Donaustauf, Germany, called the Walhalla. In German, the W is pronounced like a V, so it would be pronounced as Valhalla, the place where warriors go upon death.

If I get to Nashville, I'll definitely go to the Parthenon there to see what the Athen Parthenon looked like in antiquity.
