The Pantheon is probably the most awe inspiring building, a dome that would be difficult to recreate today,
and probably the most intact ancient monument in Rome. Trajans column is another marvel, for anyone with
a sense of history.
By the way, some of the restaurants are in old cellars, I had a fish soup as a first ( of four), courses, and have never,
before or since, tasted anything quite like it, it was the literally the most delicious thing I've ever tasted.
