Also within the main square is the excavated half of a Roman amphitheater. It appears that some modern seating has been added.
Around the perimeter of the amphitheater are some stone structures.
During some free time, I wandered off on my own, and found this courtyard.
I also found the duomo (cathedral).
After a change in direction, I found a fountain that included some organ pipes.
After all this sightseeing, we had a pizza lunch at Il Ristoro dei Templari, and then headed off to our next destination.
