Roccabruna in its actual state. Originally had a panoramic pavilion on its upper floor.
South of the Canopus is the higher and most secluded part of the Villa Hadriana (not
completely open to the public), which still is a private property and just recently was
partly cleaned-up and restored. It is a vast artificial esplanade, which had a long
containment wall with buttresses on it west side (more than three hundred meters), spanning
all the way from north - Roccabruna (n. 29) - to south - Accademia (n. 30-31) and Odeon (n.
) is the only buiding of this area open to the public; only
its lower part is preserved, with a ramp climbing on its roof, where originally there was a
round temple-like panoramic Pavilion. In its lower floor is still visible a vast rounded
internal hall, once paved with precious marbles, decorated by niches and ample windows
overlooking the landscape. There also was a series of flanking rooms, surrounding the
central hall, with stairs linking its various floors; one of these stairs climbed up to the
Panoramic Pavilion of the upper floor.
Recent restorations have found mosaic pavements;
little is left of the opus sectile
The western side of the Accademia and Roccabruna esplanades had a containment wall
more than 300 meters long.
Roccabruna had the shape and the function of a tower, similar to that of the Tempe
Pavilion: it was the only passageway and check-point leading to the esplanades of
Roccabruna and Accademia; there was no other access to them on this side of the Villa.
South of Roccabruna is a great artificial esplanade, reaching up to the Accademia
), not open to the public and still the property of the Bulgarini family,
that built a Casino over its ruins and excavated it since the XVII Century. The western side
of the esplanade still has a containment wall with buttresses, which had the appearance and
function of a city walling, which protected this side of the Villa (such as the Tempe
The northern part of the Roccabruna artificial esplanade has a smaller width,
about 35 m.; then it widens up to almost 110 m.,
with a containment wall that was at a right angle with the one coming from Roccabruna. This passage was one of the many security
check-points of the Villa; very little is known about this area which probably was a garden,
although some scholars believe here was a wood where the Emperor could hunt.
Three hundred meters from Roccabruna, on the southern end of the esplanade, is one of the lesser
known and most interesting buildings of the Villa, the Accademia
Its first visible structure are the ruins of its entrance Pavilion or Vestibulum
we can still see three of its four pillars, which originally supported some kind of roofing: Hansen believed it was a dome, other scholars have different
opinions. Two small stairs gave access to the Pavilion from the Roccabruna and
Accademia esplanades, and were a security filter controlling the entrance. Nearby, the plans by Contini and
Piranesi show a staircase climbing up from the containment wall and the road that surely
flanked it. Here were found the statues of Centaurs by Aristeas and Papias, now in the
Capitoline Museum of Rome.
One of the remaining four pillars of the entrance Pavilion of the Accademia.
Three rooms of the Accademia were stransformed in hay-stacks; the central one
still has parts of the stucco ceiling.
The entrance Pavilion lead into the vast internal garden
of the Accademia, which was
surrounded by a porch. Its high walls make it a secret and secluded garden, and probably
were meant to shelter it from the wind, since it is on the top of the hill. But there were
openigs for the view: on the western side of the garden there was a double porch (similar to
the one of the Pecile): a large door at the center lead to the outer porch, overlooking
another artificial terrace and the panorama.
On the northern side of the inner porch still exist three rooms, which were transformed in
, whose ceilings still have their stucco
The so-called Temple of Apollo is one of the best preserved structures of the Accademia.
On the eastern side of the inner porch the best preserved structure is the so-called
Apollo's Temple (Tempio di Apollo)
). It is a vast circular hall, more
than 12 meters of diameter, but only half of it is still standing. The lower part of its
walls was decorated by brick columns supporting an architrave. The upper part had windows
and niches, and according to most scholars it was covered by a dome, but there are no traces of collapsed fragments on the ground.
On its eastern side, the
Apollo's Temple opened over a rectangular alcove, where was found the famous Dove Mosaic now
in the Capitoline Museum of Rome. Its walls were completely reveted with marble and there
are traces of rectangular panels or possibly marble reliefs.
South of the Apollo's Temple is a vast apsed hall called Zooteca
(a place for
sacrifice animals, according to Ligorio); its walls have holes for the beams, that once supported the roof of a porch surrounding an inner garden.
In the center of the apse a door lead to another room, which was the concealed
entrance to the Accademia on its southern side. This room belonged to an axial perspective
from north to south, from the Accademia esplanade to the Zooteca.
A view of the substructures under the east side of the Accademia.
The so-called Zooteca, south of Apollo's Temple.
The plans by Contini, Piranesi, Winnefeld and Salza Prina Ricotti show a series of buildings
south of the Accademia garden porch. Today they are not visible anymore, hidden by a small
Casale and by the Casino buit by the Bulgarinis. According to Piranesi in this area there
were thermal plants.
The eastern side of the Accademia esplanade had its own cointainment walls, almost
completely hidden by vegetation. They passed behind the Canopus with a diagonal bearing,
until they reached the Apollo's Temple, under which the wall became a cryptoporticus. Here
was a vast area which reached east to the Inferi (n. 33). Ancient maps by Piranesi show the
existence of secret subterranean passageways also under the central garden of the Accademia.
The ambulacrum of the Odeon, the theater near the Accademia.
The remains of the Scenae frons of the Odeon theatre.
Further south are the ruins of the place where, at the end of the XV century, were held the
oldest excavations we know of: a theater called Odeon
), from which
come the statues of seated Musae
now in the Prado Museum of Madrid, Spain. Little is
visible of this building, just the rear part behind the scene; the scenae frons is barely
visible in the wood, while the cavea is completely hidden by the vegetation.
A series of subterranean galleries linked the Odeon to one of the most peculiar and little
known buildings of the Villa, a nymphaeum called Inferi
Formerly a tufa quarry, this is an arficial valley excavated in the tufa rock, with a
central grotto at its southern end, decorated by a cuniculus

The grotto of the Inferi, with the central operning for a water fountain. The rock was
chiseled to simulate a natural grotto, and partly reveted with 'tartari', fake stalactites,
made of travertine.
The grotto was flanked by two openings which gave access to subterranean corridors excavated
in the tufa bank, linking it to the Odeon and also to the Great Trapezium (Grande
The Great Trapezium is a subterranean road network, probably for the carts bringing supplies
to the Villa Hadriana. Salza Prina Ricotti believes that one of these galleries, which has a
series of niches, was used as a stable for horses and mules. Actually this comblike
structure is typical of the cuniculi
, subterranean galleries for the drainage of
water, very frequent in roman and etruscan area. It is possible that these cuniculi

belonged to the ancient republican villa later enclosed in the imperial buildings.
Since the Great Trapezium is linked by subterranean galleries with the Odeon and the Inferi
grotto, Mac Donald and Pinto (1995) suggested instead that this subterranean road system
– absolutely unique in its own kind – had a symbolic meaning linked to the
Afterworld and possibly to the Eleusinian Mysteris (about which very little is known). This
hypotesis is very interesting and is supported by the presence of the Odeon, since theaters
were often used for symbolic and ritual representations.
The Mausoleum as was visible in the XIX century in an engraving by Penna.
Further north still survive the remains of a Mausoleum
actually is covered by a thick bush. The XIX century engraving by Penna shows it in a better
state of preservation. It is supposed to be a funerary monument, but Mac Donald and Pinto
(1995) believe it could have been instead a "Neviera" a building meant for preserving the
snow in summer-time.
Recent excavations of the site by professor Patrizio Pensabene discovered several fragments of
columns and marbles, and also opus sectile
pavements. Therefore this building was not a
Mausoleum nor a snow storage structure, but a small round temple.
Not far from the Mausoleum is the Temple of Pluto
), about which
almost nothing is known. Its state of preservation is fragmentary, old maps show a rectangular
bulding with a central apse on one of its long sides. On the spot are still visible mosaic
fragments, opus sectile
, and some walls.
In the Bulgarini estate are still visible the ruins of the aqueduct that supplied the
Still in the Bulgarini Estate are visible the remains of an aqueduct
(not shown in
plan) partially hidden by ivy. Villa Hadriana had a general leaning from south to north, so
the water supply must have come from south and from above. This aqueduct, which an engraving
by Penna shows in a far better state of preservation, in the first decades of the XIX
century, surely was linked to one of the great public aqueducts which brought water from the
Aniene river in Tivoli to Rome.

Further south (again not shown in the map) there was a double porch

which probably belonged to a different Villa.
