The Aventine Hill is one of Rome’s most seductive spots. The view from the Parco degli Aranci spans across the medieval bell towers of Trastevere, over the budding trees along the Tiber river, and all the way to the massive four-sided cap of the synagogue in the Jewish Ghetto. The dome of St. Peter’s basilica above a dark blanket of umbrella pines on the Gianicolo in the distance makes a perfect backdrop. The view alone is well worth the effort to climb the highest of Rome’s seven hills during most of the year, but in the spring you would be better off exploring the Aventine hill with your eyes closed. In fact, the sense of smell is really all you need on the Aventine right now. At the top of the hill, the peppery essence of laurel trees blends with the bubblegum perfume of the wisteria that sprawls along the stone walls. Down the hill, the first hint of musky jasmine flowers mixes wonderfully with the sweet-smelling blossoms on the orange and lemon trees. From late March, when the bright Mimosa trees burst into their pungent yellow bloom, the Aventino puts on a sort of olfactory concerto that lasts well into summer. In a few weeks, the roses in the Roseto Comunale (the city’s rose gardens on the site of a former Jewish cemetery) will add a new layer to the bouquet.
