Recently I’ve been evangelizing for “slow travel,” a leisurely way to see more of the world by consciously seeing less of it. It sounds contradictory but there’s a reason why it works. Travel provides an extraordinary opportunity to learn about people and cultures and place them in their historical and contemporary contexts. Slow travelers begin by reminding themselves that they can’t see it all. They are students of world history, geography, art, music, architecture, anthropology, languages – what Zorba called the “full catastrophe” (never mind that he was talking about marriage and family; the phrase covers all situations). Here are four famous attractions that you should avoid unless you have ample time in Rome.
