This Villa is located on a hill near the Tyrrhenian Sea in southern Lazio, at the foot of a massive spur of the Ausoni Mountains. These barren mountains, which constitute an impassable barrier between the fertile Piana di Fondi and the coast, are now included in the Regional Natural Park of the Ausoni Mountains and Lake of Fondi. In 184 BC the censor L. Valerio Flacco built (perhaps by restructuring a pre-existing path) a daring hillside road that passed through here, joining Terracina to Gaeta: the modern Via Flacca partly follows this path.
At km 16.300 of the Via Flacca (modern panoramic coastal road which, parallel to the Via Appia, which runs inland, joins Terracina to Gaeta and Formia) stands the Archaeological Area of the Villa of Tiberius. This site, beautifully located near the sea, is made up of the Imperial Villa (with the relevant CAVE) and the National Archaeological Museum of Sperlonga.
The sumptuous Villa of the Emperor Tiberius was built on a pre-existing villa of the Republican age; the first structures are in fact related to a late republican residence, possibly belonging to Aufidio Lurco (maternal grandfather of Livia, wife of Augustus). Tiberius (who succeeded Augustus in 14 AD) used this residence until 26 AD; in that year, worried about the occurrence of a landslide that hit him during a banquet, the Emperor preferred to move to Capri.
