Yes, in the middle of Centennial Park there is a full-scale replica of the Parthenon, the crown jewel of the Acropolis in ancient Athens. The Nashville replica is supposed to be complete and accurate in every detail, including the statue of Athena inside. The Nashville Parthenon also houses an art museum.
I didn’t go inside to see Athena — the presence of groups of schoolkids seemed to promise a less than pleasant experience for a hefty $6 price tag — but I did walk around the structure, which is being refurbished. It’s a pretty cool thing to find in the middle of an American city.
