As I have said, I am in the USA tracking Roman emperors, which has taken me to a surprising variey of different locations, including --en route to other things -- to the Parthenon in Nashville. The original replica building was put up for the Centennial Exhibition in Tennessee in 1897. And in the 1920s it was made permanent in fairly tasteful concrete.
It was only over the last couple of decades that the sculptor Alan LeQuire, who -- I should say -- was really helpful to me when I was writing my book on the Parthenon, first made and then gilded the replica of the cult statue. So you now walk in to see something that tries to approximate to the original experience.
