La villa privata delimitata dal muro di cinta in Via Marconi conserva imponenti resti del I-III sec. d.C. denominati “Terme Nettunie”, ma forse pertinenti a una villa suburbana decorata da pitture lineari e un mosaico con mostri marini. Dall’esterno è visibile, attraverso un’apertura nel muro, solo un tratto dell’Appia traianea. Nel Medio Evo fu ricavata nelle cisterne romane la chiesa della Maddalena con annesso lebbrosario; del complesso religioso, gestito dapprima dai Templari e poi dai Cavalieri di S. Lazzaro, rimangono tuttavia solo evanescenti pitture. L’area venne in seguito adibita a orto e agrumeto da Pio VI, che fece costruire una nuova casa al di sopra della chiesa.

The private villa, which is surrounded by a wall belt along Via Marconi, keeps the imposing ruins of the “Baths of Neptune” belonging to the 1st-3rd cent. A.D.; perhaps they are part of a suburban villa with linear paintings and a mosaic floor with sea-monsters. From the outside, through an opening in the wall, you can see just a stretch of the Trajan Via Appia; during the Middle Ages the Roman cisterns were converted into the church of Maddalena with a leper hospital adjoining to it. Just some unclear paintings can be seen in the religious building which was run, at first, by the Templars and, later on, by the Knights of S. Lazzaro. Then the area was used as an orchard and citrus grove by pope Pius VI who ordered to build a new house above the church.
