A bronze statue to Diana the Huntress greets you at the entrance to Nemi, the smallest and prettiest village of the Castelli Romani. It's perched on a spur of rock 600 feet above the little oval-shaped lake of the same name, which is formed from a volcanic crater. Nemi has an eagle's-nest view over the rolling Roman countryside as far as the coast, some 18 km (11 miles) away. The one main street, Corso Vittorio Emanuele, takes you to the baronial Castello Ruspoli (not open to the public), where there's an 11th-century watchtower, and the quaint Piazza Umberto 1, lined with outdoor cafés serving the tiny wood strawberries harvested from the crater bowl.
If you continue on through the arch that joins the castle to the former stables, you come to the entrance of the dramatically landscaped public gardens, which curve steeply down to the panoramic Belvedere terrace, with a café that's open in summer. A pedestrian-only road runs down the crater side to the Roman Ships Museum. Otherwise, car access is from the town of Genzano on the opposite side of the lake.
