Yes, you are seeing that correctly. It's a full size replica of the Parthenon in Athens. Right in the middle of Nashville, Tennessee. It was built in 1897 as part of the Tennessee Centennial Exposition.
It's a beautiful structure in a nice park. On warm days, there are families and groups of friends relaxing, tossing a frisbee and just having a good time. The structure itself is immaculate.
I like the way this photo shows the detail in the building. The way the green light makes it stand out against the deep blue early morning sky as it gives way to the rising sun. And even though my centering wasn't dead on, I like the pathway leading into the building.
Mostly though, it just blows my mind that someone would build an exact replica of the Parthenon in Nashville, Tennessee in the 19th century.
