How does one take a photo of a major world landmark that doesn't just look like every other tourist shot of the same site? One technique I use is to zoom in to capture detail that the more usual wide shots don't see. I think this one worked well; I have a framed enlargement of this photo hanging on a wall.
You can see some of the scaffolding that is there for preservation work. At large size you can also see some of the holes in the travertine limestone where the original marble cladding was anchored and then later removed.
