"On my first trip to Rome, I did as the tourists do: paid my respects at the Colosseum, Trevi Fountain, Spanish Steps, Vatican, and no fewer than a dozen gelato shops. But the memory that lingers strongest a decade later is of boarding a nondescript commuter train to Parioli with my friends to visit the Moschea di Roma, the largest mosque in Europe. Built in 1994 with the blessing of Pope John Paul II, it is a tranquil escape from the eternal frenzy of the Eternal City."
