For me, this old arch was a 5 on the scale of historic attractions. As I looked at it, I wondered about life here when it was first constructed. They were very different times.
You need to be in relatively good shape if you plan to make the walk down over the hill from city center to see the arch because the hill is fairly steep. However, if you make the walk, you will become witness to the engineering and masonry skills of a people (Etruscans) who lived long ago.
Looking at the wall again, I knew that on the day they were finishing the arch, those who constructed it could have had no idea what the world would look like today. You can see my trip to the wall was a philosophical journey through time. I loved it!!
