In a city so filled with icons of antiquity and the Christian faith, it's hard to know where to go first. Of course, your own interests will govern your choices, but there are certain sites that are almost obligatory landmarks of Italy and of all Europe, such as the Colosseum and the Pantheon. A word of caution: try to vary your experiences as you explore Rome, so that you don't visit too many ancient sites or churches in a row. And intersperse these more serious attractions with a few that are simply tourist icons - the Spanish Steps and that place all tourists must go to toss in their coin, the Trevi Fountain. Rome is so big that it can overwhelm, so even the most devoted sightseer should take some time to kick back and enjoy la dolce vita in a park or sidewalk café.
