Villa Gabrielli al Gianicolo
Italy
Villa Gabrielli was an urban villa in Rome. It once comprised a large plot of land on the northernmost part of the Janiculum, just west of the Tiber. Today its land has been divided among the present campuses of the Pontifical North American College and the Pontifical Urban University. The construction of various buildings from 1869 until the present day has significantly altered the original layout of the villa's park, which survived largely intact into the twentieth century.
