Nero built the Domus Aurea after the 64 AD fire cleared a third of Rome. Up to 300 hectares of private palace, gardens, and artificial lake — including a 30-metre golden statue of himself as the sun god whose name gave the Colosseum its name. His successors stripped it, filled it with rubble, and built over it. The backfill that buried the frescoes also saved them. When Raphael and Michelangelo were lowered through holes in the Oppian Hill in the early 1500s, they found Fabullus's fantastical painted ceilings above them and named the decorative style 'grotesque' after the grotte (caves) where they found it. The style is still called grotesque today. The Octagonal Hall's concrete dome was Brunelleschi's study model for the Florence Cathedral dome. Weekend-only tours, advance booking required, €16–22.

The Domus Aurea (Golden House) was the palace complex built by the Emperor Nero (r. 54–68 AD) in Rome following the great fire of 64 AD. The fire cleared approximately a third of the city; Nero used the destruction to appropriate the land and build a palace of unprecedented scale — 80 to 300 hectares of private space (sources vary) stretching from the Palatine Hill across the valley (where the Colosseum now stands, where Nero built an artificial lake) to the Oppian, Caelian, and Esquiline hills. The palace complex included gardens, forests, vineyards, a 30-metre golden statue of Nero as the sun god (the Colossus Neronis, which gave the Colosseum its name when Hadrian moved it), and the main palace building decorated with gold leaf, mother of pearl, semiprecious stones, and frescoes painted by Fabullus — the most famous Roman painter of his era, of whom virtually nothing else survives.
Nero was assassinated in 68 AD. His successors — the Flavian dynasty and then Trajan — had the Domus Aurea stripped of its decorations, filled with rubble, and built over: the Baths of Titus (80 AD), the Baths of Trajan (104–109 AD), and a gymnasium were all constructed on top of the buried palace. The result was that the Domus Aurea's rooms were sealed and preserved — the backfill that buried the frescoes also saved them from the lime-burning that destroyed virtually every other Roman fresco complex in the city. When Renaissance artists — including Raphael, Michelangelo, and Ghirlandaio — were lowered through holes in the ground into what they thought were underground caves (grotte), they found the frescoed ceilings above them and developed an artistic style based on those frescoes that they called "grotesque" (from grotta). The term is still used in Western art and decoration.
The surviving section of the Domus Aurea is approximately 150 rooms of the original palace building, now underground beneath the Oppian Hill park. The rooms accessible on the tour vary by programme (VR tour options, standard archaeological tour, combined options). Key spaces:
The Octagonal Hall (Sala Ottagonale): the architectural centrepiece of the surviving section — an octagonal room with a concrete dome of extraordinary technical sophistication for 68 AD, with an oculus (central opening) that allows natural light to fall in a rotating beam across the floor as the day progresses. The room demonstrates Nero's architects (Severus and Celer) working at the absolute frontier of Roman concrete engineering, producing a dome form that would not be seen again in the Mediterranean until the Renaissance. This specific dome was the technical model that Brunelleschi studied before designing the Florence Cathedral dome.
The fresco rooms: sections of the Fabullus fresco programme survive in varying states of conservation — deteriorated by centuries of damp from the Trajan baths above, but still legible in places. The grotesque style (the fantastical decorated-border compositions that Renaissance artists copied) is visible in the upper sections of several rooms where the damp has been less destructive.
The ongoing restoration and AR programme: The Domus Aurea has been developing augmented reality and projection technology to show the rooms as they originally appeared, with the gold and fresco decoration restored to the bare concrete and brick walls. This component varies by tour type and budget allocation; check the current offer at the time of booking.
Booking: The Domus Aurea is accessible only on guided tours, bookable through the official Parco Colosseo website (parcocolosseo.it) or by phone. Opening is currently limited to weekends and holidays — check current schedule and availability as the programme has varied significantly. Tours in English and Italian. Entry: approximately €16–22 depending on tour type (standard archaeological, VR-enhanced, or special night tours at higher prices). Getting there: Metro B, Colosseo stop (the Domus Aurea entrance is on Via della Domus Aurea, on the Oppian Hill side of the Colosseum — 5 minutes on foot from the Colosseum). Clothing: The interior temperature is approximately 10–12°C year-round; bring a layer regardless of outside temperature. Combine with: The Colosseum (adjacent, book separately); Colle Oppio park above the Domus Aurea; and the free exterior circuit of the Colosseum.
The Domus Aurea (Golden House) was Emperor Nero's palace complex built in Rome after the great fire of 64 AD. Covering up to 300 hectares with gardens, forests, artificial lake, and a 30-metre golden Nero statue, it was the largest private residence in Roman history. Stripped and buried by Nero's successors, its sealed frescoed rooms were rediscovered in the Renaissance — when Raphael and Michelangelo were lowered through the ceiling — and the fresco style they found there became "grotesque" decoration, still used in Western art. Today approximately 150 underground rooms are accessible on guided tours (weekends only, advance booking required, €16–22).
The Domus Aurea is accessible only on pre-booked guided tours. Book through the official Parco Colosseo website (parcocolosseo.it) or by phone. Current opening is limited to weekends and holidays; the schedule varies — check at time of booking. Tours in English and Italian. Entry approximately €16–22. The entrance is on Via della Domus Aurea, 5 minutes from the Colosseum (Metro B, Colosseo stop). Bring a layer — interior temperature is 10–12°C year-round regardless of outside weather.
The Domus Aurea is significant for multiple intersecting reasons: as the most ambitious private construction project in Roman history; as the building that gave the Colosseum its name (via the Colossus Neronis statue); as the site where Renaissance artists developed the "grotesque" decorative style (from grotta — cave) that has influenced Western decoration for 500 years; and for the Octagonal Hall, whose concrete dome technique was studied by Brunelleschi before he designed the Florence Cathedral dome. The ongoing archaeology continues to reveal new aspects of the most technically and artistically ambitious Roman palace complex.
The Octagonal Hall (Sala Ottagonale) is the architectural centrepiece of the surviving Domus Aurea underground section — an octagonal room with a concrete dome of extraordinary sophistication for 68 AD, with a central oculus that admits natural light in a rotating beam across the floor through the day. The dome demonstrates Nero's architects (Severus and Celer) working at the frontier of Roman concrete technology. Brunelleschi specifically studied this room's structural principles before designing the dome of Florence Cathedral (1420s). The combination of the octagonal plan, the concrete dome, and the oculus makes this room technically the most important surviving Roman interior in Italy.
The term "grotesque" in art and decoration derives directly from the Domus Aurea. When Renaissance artists — including Raphael, Michelangelo, and Ghirlandaio — were lowered through holes in the Oppian Hill into the buried and forgotten Domus Aurea rooms (which they assumed were underground caves, grotte), they found the frescoed ceilings above them: the Fabullus fresco programme showing fantastical combinations of figures, foliage, architecture, and mythological scenes in decorative borders. This style became enormously influential in Renaissance decorative arts and was named "grotesque" (grotesca) after the grotte (caves) where it was found. The style appears in Raphael's Vatican Logge, in the fresco decorations of countless Renaissance palaces, and in subsequent centuries of Western decorative design.
The Domus Aurea is worth visiting for visitors with genuine interest in Roman history, Renaissance art history, or architectural history. The Octagonal Hall alone — the most significant Roman concrete structure surviving in Rome — justifies the visit. The grotesque fresco context, the specific archaeology of a buried imperial palace, and the ongoing AR/projection interpretation make it one of the most intellectually rich single-site experiences in Rome. The limitations: weekend-only access, advance booking required, relatively short tour duration (60–90 minutes), and the deteriorated state of many of the frescoes. Best combined with the Colosseum on the same day.

Plan my Rome trip →The original Domus Aurea covered an area that ancient sources and modern archaeologists estimate at 80 to 300 hectares — the range reflects both the ambiguity of ancient descriptions and the difficulty of establishing what was within the palace complex versus adjacent but separate land. The central palace building (the portion now partially underground on the Oppian Hill) covered approximately 15 hectares; the overall complex including gardens, the artificial lake (stagnum), vineyards, pastures, and the support buildings covered the valley between the Palatine, Oppian, Esquiline, and Caelian hills. Suetonius wrote that the vestibule of the Domus Aurea was large enough to contain a 30-metre-tall statue of Nero (the Colossus Neronis, which gave the Colosseum its name when Hadrian moved it).
Nero was assassinated in 68 AD. The Flavian dynasty (Vespasian, Titus, Domitian) systematically dismantled the Domus Aurea as a political statement: the artificial lake was drained and the Colosseum built on its site (completed 80 AD); the Baths of Titus were built on top of part of the palace. Trajan filled the remaining palace rooms with rubble (to provide structural support for the Baths of Trajan above, completed 109 AD) and buried the complex. Nero was condemned by the Senate after his death (damnatio memoriae — official erasure of his name and image); the destruction of his palace was part of this symbolic erasure. The result — the backfill that saved the frescoes — was the specific historical accident that allowed Renaissance artists to find them 1,400 years later.
Fabullus (also known as Famulus) was the Roman painter commissioned by Nero to fresco the Domus Aurea — described by Pliny the Elder as working only for a few hours each day while dressed in his toga (a detail that Pliny found remarkable and possibly eccentric). Virtually nothing by Fabullus survives outside the Domus Aurea; the palace frescoes were his primary documented work. The style — fantastical combinations of architecture, landscape, mythological figures, and decorative borders — in the Domus Aurea rooms was what Renaissance artists found when they were lowered through the ceiling, and the term "grotesque" (from grotta) applied to this style has remained in art history and decorative arts since the 16th century.
