After a devastating fire destroyed much of central Rome in 64 A.D., Emperor Nero ordered the construction of a palace that would come to be known as the Domus Aurea — “Golden House” in Latin.
This imperial complex covered nearly 125 acres in the heart of the city and was renowned for its scale and opulence.
Yet the complex was deliberately buried when the emperor Trajan ordered it covered under tons of earth and rubble, repurposing it as the foundations of his baths.
Today, what survives lies beneath the Oppian Hill, preserved — ironically — by the very material meant to conceal it.
How Was Nero’s Domus Aurea Built?
The architects Severus and Celer designed Nero’s residence, while the painter Famulus oversaw its decoration. The result of their collaboration was remarkable by any measure.
The complex was not a single building but a sprawling network of structures set among forests, gardens, vineyards, and an artificial lake. Its technical achievements were extraordinary for the era.
The octagonal hall, for instance, featured a concrete dome with a central oculus that drew in natural light — an architectural breakthrough that prefigured the Pantheon.
The most lavish section of the Domus Aurea stretched across the Palatine and Oppian hills. Walls were lined with gold leaf, precious stones, and frescoes by Famulus, the artist credited with defining the Fourth Style of Roman wall painting.
The complex also included baths supplied by thermal and sulfurous springs, grand banquet halls, and an entrance vestibule dominated by a colossal statue of the emperor.
After Nero’s suicide, however, this display of excess was systematically dismantled. The grounds were repurposed as an instrument of political legitimacy for the new rulers. Where Nero had kept a private lake, the Flavian dynasty raised the Flavian Amphitheater — known today as the Colosseum.
The chambers of the Golden House were stripped of their marble and filled with rubble and earth to support the weight of the Baths of Trajan. Paradoxically, this act of erasure became an act of preservation: sealed from oxygen and light for centuries, the original paintings survived.
The accidental rediscovery of these rooms in the 15th century reshaped Western art. Painters, including Raphael, descended into what they called the “grottoes”—the buried halls—to study the frescoes. From that encounter emerged the “grotesque” decorative style that would spread throughout Renaissance art and architecture.
Today, visitors to the Domus Aurea site can take in the scale of the Roman retaining walls that cut through what were once banquet rooms. Current efforts focus on restoring the frescoes and reducing the structural pressure the gardens above place on the ancient vaults.
What was once a monument to imperial isolation has become a testament to the fragility of power in the face of time. The Domus Aurea is not merely an archaeological site — it is the physical record of a failed attempt to bury history beneath architecture.
