3 Best Sights in Mergellina and Posillipo, Naples

Atop Posillipo's hill, this small yet magical complex has a 1st-century villa and two amphitheaters; access is though the Grotta di Seiano, a 2,500-foot tunnel cut though the tufa rock over two millennia ago. Guided tours (in Italian, book ahead) are given at 11 weekdays, 10:30 and 12:15 on weekends and holidays. Evening concerts are often held here in the summer.

An often overlooked sight in western Naples, this park—not to be confused with the Parco Virgiliano, at the western end of the Naples suburb of Posillipo—is named for the poet Virgil and is reputedly his burial site. The sign at the entrance indicates that not only (by legend) is Virgil's tomb here, but also the tomb-memorial of Giacomo Leopardi, the author of the evocative poem "L'infinito," who died during the 1837 cholera epidemic. As a safety precaution, victims of the disease were usually buried in mass graves, but the writer (and later politician) Antonio Ranieri, a close friend, arranged for this monument, which until 1939 was located elsewhere. From the Mergellina metro station, walk south to Salita della Grotta and turn right just before the church of Santa Maria di Piedigrotta; the park's entrance is just before the road tunnel.

Perched 500 feet above the Bay of Naples, this large urban park is worth the trip for its stunning vistas that face the islet Nisida with the formerly industrial area of Bagnoli stretching out below. A raised central area has a sports field where the Naples American Football team often trains.
