My main goal of visiting Rome was the Vatican, so I visited the Eternal City somewhat incidentally, but rather superficially. The weather was not kind, and the sun, appearing and disappearing behind dark clouds every now and then, drove me to despair. However, I could not resist seeing at least the outside of the Colosseum, the Pantheon or the Trevi Fountain. There were crowds of tourists in all of these places, which significantly worsened the comfort of sightseeing.
