Take a virtual tour into the past and visit the Basilica of Maxentius - the largest building that was built on the Roman Forum! Our reconstruction reproduces in detail the design and decor of this basilica and in 15 minutes of this mini-film you will see both the appearance of the basilica with the surrounding buildings and its magnificent interior, as it was in the 4th century. Particular attention is paid to the comparisons "now and then" from the same points.

The Basilica of Maxentius was the largest building in the Forum Romanum. Those colossal ruins still
amaze us today. In this video, we will take a detailed look at what it was like during its
time of glory. Let's go! The basilica was erected in the early 4th century and was part of Emperor
Maxentius' grand program to restore and rebuild this most important and central part of the city.
It can be said that Emperor Maxentius carried out the last major architectural changes
in ancient Rome, which were in keeping with its ancient history.
Basilica stands on the north side of Sacra Via, on land previously at least in part covered by
Domitian Floria Peperataria. It stood on a platform of concrete raised a story above the
Sacra Via at its west end. This was 100 meters long and 65 meters wide. It is the last of the
great secular basilicas of Rome and still remains a great shell of brick-faced concrete, which owes
more in design to the great central halls of the imperial baths than it does to classical basilicas.
When we soon see the interior, we will notice how similar it is to the vast halls of the baths of
Caracalla and Diocletian. The site for this enormous basilica was chosen in the very heart
of Rome, on the Via Sacra, between the Colosseum and the Forum Romanum, and in close proximity
to the Temple of Venus and Roma and the Forum of Peace. The building faced the street
with its long southern facade. The massive basilica was visible from afar.
Now we will approach it from the east, from the direction of the Colosseum.
We are flying past the Colossus and will soon see the eastern facade of the basilica,
from the eastern side. And now we will approach the Basilica of Maxentius from the west,
from the Forum Romanum side. Leaving the Forum behind, we see the Via Sacra and the imposing
southern facade of the basilica. Here we see the same southern facade, but this time from the
hill. There was another entrance to the building here. It was previously believed that Constantine
changed the design by adding a new entrance in the middle of the southern side. However,
there are now strong arguments supporting the idea that this design was originally conceived
by Emperor Maxentius, and Emperor Constantine's role in the reconstruction of the basilica was
minimal. Here a flight of steps led up from the Via Sacra to a shallow porch with a series of
porphyry columns framing three double doors. The basilica had two apses on the eastern and
northern sides, both built under Maxentius. The northern apse was part of a complex system of
retaining walls on this side, which were necessary to ensure the stability of the structure.
Concluding our overview of the basilica's exterior, we will look at it from the side
of the Arch of Titus. On the right, we see the Temple of Venus and Roma. Now we can see the
Basilica of Maxentius along with the Via Sacra and the perspective of the Forum Romanum in the
distance. Now we will move on to the interior. We enter the basilica through the entrance on
the eastern side. As we walk along the main longitudinal axis of the basilica towards
the western apse, we reach the place where a colossal statue was located. The western apse
was vast, 20 meters in diameter, with a half-dome. This probably became the setting of a seated
Colossus of Constantine, which was rebuilt from Maxentius and which was in his turn rebuilt from
the 2nd-century emperor. Parts of this acrylic statue were found in 1486 and are now displayed
in the courtyard of Palazzo dei Conservatori. Now we will enter via the staircase on the southern
side, from the Via Sacra. As we move along the short transverse axis of the basilica,
we find ourselves facing the northern apse. The basilica was richly and elegantly adorned.
Expensive types of marble, gilding, stucco, and paint were used. We will now demonstrate this
by using then and now comparisons. A central nave was 80 meters long, 25 meters wide, and it was
flanked by side aisles. It was vaulted by a great cross-vaulted roof, which reached about
35 meters high, appeared supported on eight monolithic columns of Proconnesian marble.
Side aisles divided into three aqueous sections, communicating with the nave along their
hall with and with one another by generous archways. Big round-headed windows in two zones,
six to a room, lit the chambers of the side aisles. The floor was paved with colored marble
in a pattern similar to that of the Pantheon. Niches for statuary abound in the interior,
and presumably the exterior was similarly embellished as well.
The eastern entrance was to be from a short street leading off the Sacra Via. Here a
single-story narthex, eight meters deep, preceded the building. This had five entrances to the
basilica proper, three to the nave and one to each side aisle, but only two to the exterior
on the east. Vaults and interior were finished with stucco, painted and gilded. The walls
were covered with marble up to the springing of the vaults. Several expensive sorts of marble
were used, including pavonosetta and giallo antico. Opposite the southern entrance,
on the short axis, there is an apse on the north wall, somewhat lower than that in the west end,
screened from the nave by a pair of columns which must have carried a straight epistyle.
This was presumably a designated area for private court proceedings.
Everything was vaulted in this basilica, and all the vaults were deeply covered in elaborate
patterns of octagons, hexagons and lozenges. Triple-wide arched windows of the type familiar
from bath complexes opened in the clerestory of the nave. The building was a triumph of
engineering, the central nave having been the largest cross-vaulted hall in antiquity and
supported by an ingenious system of flying buttresses. The basilica was a great masterpiece
and has been admired by architects and artists throughout its history. It was exhaustively
studied by the High Renaissance, and its impact on such architects as Bramante, Raphael, Antonio
da Sangalo and Michelangelo was immense. Its influence on the design of the new Basilica
of San Pietro is readily apparent. Basilica remained in use several centuries,
even in the Middle Ages, but it had lost its proper designation then and was called
The south aisle and nave probably collapsed in the earthquake of Pope Leo IV in 847.
By the 16th century, the basilica already had its current appearance. Only one of the eight
internal columns remained in place. It was moved to Piazza Santa Maria Maggiore in 1614.
Thus, the ancient shaft of the column has survived to this day.
The capital of the column is not ancient and was added during the reconstruction.
And finally, here's a little bonus, a simulation of the basilica's destruction
that I tested a few years ago in a game engine. One day I plan to create a new simulation with
a complete 3D model and these appropriate effects. Thank you for watching this video.
