We got back on bus and headed for the Trevi Fountain. I threw in a coin, to make sure that I would come back to Rome! Very impressive in a very small space... with lots of people.
We continued on our tour to the rest of the route, and then walked over to the Pantheon. This is a fascinating building, built in 125 AD. We returned on the bus to our hotel so that we could pick up our rental car. Tomorrow, on to Tuscany.
It seems appropriate that our trip started in Athens, with one of the stops in Egypt, which pre-dated the Parthenon, and will end in Rome, with its huge impact on the Western World. If I wanted a course on the history of Western Civilization, this trip provided the authentic resources.
