The buildings are constructed in
travertine, brick,
lime,
pozzolana, and
tufa. Villas were typically sited on hilltops, but with its fountains, pools and gardens, Hadrian's villa required abundant sources of water, which was supplied by aqueducts feeding Rome, including the
Aqua Anio Vetus,
Aqua Anio Novus,
Aqua Marcia, and
Aqua Claudia. To avail themselves of those sources, the villa had to be located on land lower than the aqueduct. The complex of the villa contains many structures from different cultures. For example, the villa has a small river running through it which relates back to the Egyptian
Nile river. The villa contains several Greek figures called Poikilos. All surviving written evidence of Hadrian's Villa in ancient writing is from the
Historia Augusta, which describes how Hadrian named rooms of the villa after various significant locations within the Roman Empire (the Lyceum, the Academy, Hades) and these continue today to be the terms scholars use to describe sections of the villa. This area's sculptural program is the most complete including copies of famous sculptures including the
caryatids of the
Erechtheion, a statue depicting the Egyptian dwarf and fertility god
Bes, and a crocodile. One structure in the villa is the so-called "Maritime Theatre". It consists of a round portico with a barrel vault supported by pillars. Inside the portico was a ring-shaped pool with a central island. The large circular enclosure in diameter has an entrance to the north. Inside the outer wall and surrounding the moat are a ring of
unfluted Ionic columns. The Maritime Theater includes a lounge, a library, heated baths, three suites with heated floors, washbasin, an art gallery, and a large fountain.
The Antinoeion In 1998 a new section of the villa, named by scholars the Antinoeion, was rediscovered. This area is located on the main road leading to the grand vestibule. The discovery of a large concrete foundation has been used as evidence of the original location of the Antinous Obelisk which is now located on the Pincian Hill in Rome. The Antinoeion is just one example of Egyptianization of the villa. Artwork such as the crocodile of the Canopus and the statue of Osiris-Antinous show the prevalence of this orientalist aesthetic in the villa. == Sculptures and artworks ==
