Ponte Rotto

Last week I told someone here that I had not taken any 

photos of this bridge on my recent trip to Rome, but then saw 

that I had. It's the Ponte Rotto, or "broken bridge," aka 

Pons Aemilius, the oldest stone bridge in Rome—

built in the 2nd century BC!  Only one arch is left, and the 

new bridge directly behind it is the Ponte Palatino.
