Lavish, original, gigantic: the Domus Aurea is the symbol of the ingeniousness of Emperor Nero, and that of the First Empire, which changed the face of Rome.

Located opposite Rome’s Colosseum, Domus Aurea is perhaps the most important monument of Ancient Rome. Yet, not many people have heard about it.

During my time in Rome, I was fortunate enough to get exclusive access to the Domus Aurea for a private tour and interview with the Scientific Director of the Domus Aurea, Prof. Alessandro D’Alessio. Here are some interesting facts about the Domus Aurea which I hope will inspire you to visit it.

What is the Domus Aurea?

Domus Aurea, from Latin meaning “Golden House”, was an opulent residence built by Emperor Nero in 64AD. It was immense, decadent, and innovative, pushing the boundaries of architecture. For centuries it was lost. Then by accident, it was rediscovered during the Renaissance.

What has been excavated so far sits on the Oppian Hill and is said to have been a pavilion, not a living quarters. Due to the lack of kitchens and lavatories, archaeologists suggest it was probably used as a space to talk a stroll around and appreciate the view of the valley to the south and admire the lavish interior decorations and works of art.

Domus Aurea was the creation of an Emperor who had a deep appreciation for the arts in all its forms including music, paintings, poetry, and sculptures. Nero took great interest in every detail of the project, and according to Tacitus’ Annals, he oversaw the engineer-architects, Celer and Severus, who brought to life the palace of Nero’s dreams. On entering Domus Aurea for the first time, Roman writer Svetonio documents Nero as saying:

Great! Finally, I can start to live like a human being! – Svetonio, Nerone, 31.2

What did the Domus Aurea look like?

Domus Aurea’s extensive decorative gold leaf dazzled in the sun. Yet, that was not the only extravagant element of its decor. The walls, dressed with ornate frescoes inspired artists such as Raphael, Michelangelo, and Casanova giving birth to a new art style, Grotesque. Setting new trends during the Renaissance.

Stuccoed ceilings were dressed with semi-precious stones and ivory veneers, while the walls were frescoed, coordinating the decoration into different themes in each major group of rooms. The sound of flowing indoor fountains echoed throughout.

Each room was flooded with the warm Roman light. The interior rooms were ingeniously lit by downward sloping ‘windows’ from adjacent rooms.

All of this overlooked a valley with a grand lake. Years later this same lake was drained in order to build the Colosseum. The ability to stage fake naval battles was thanks to the lake’s water system.

Domus Aurea’s most celebrated and influential feature was the bright octagonal court that opened up to the heavens via a giant oculus in its large dome. Nothing before it had ever been built. It became the model for Rome’s magnificent Pantheon built years later and has continuously been studied and copied throughout history.

Historian Suetonius wrote a vivid description of the palace in the ‘Lives of the Caesars, Nero’. While historians were skeptical at its accuracy, a recent discovery suggests that Suetonius’ description was at least partially correct.

The main banquet hall was circular and constantly revolved day and night, like the heavens.

Archaeologists have found calcite deposits on the surrounding stones suggesting that the floor’s constant movement may have been powered by water channelled through a system of gears.

This once giant residence in the heart of Rome is now hidden. Buried. Remnants of Roman walls hint at its presence below.

Thirty-five years after its completion in 68AD, Emperor Trajan commissioned the construction of thermal baths above Domus Aurea, forcing the palace underground. Then, during the fascist regime, a park was built. Today, imposing tree roots and severe flooding threaten the structure of Domus Aurea.

In fact, sixty square meters (645 square feet) of the vault of a gallery collapsed on March 30, 2010, thus forcing the closure of the entire Domus Aurea complex for restoration.

Finally, after its reopening in 2014, the Domus Aurea is back on the tourist radar and in need of our help.

Domus Aurea is a precious and important piece of history that must be preserved and protected. (More on that later!)

How big was the Domus Aurea?

The Domus Aurea complex covered parts of the slopes of the Palatine, Esquiline and Caelian hills, with a man-made lake in the marshy bottomlands.

Its estimated size is only an approximation as much of it has not been excavated. Some scholars place it at over 300 acres.

As we know it today, there are 155 rooms, which cover 16,000m2; the equivalent of three football fields!

The ceilings here are 12 metres high and it’s estimated to have had 30,000 metres squared of frescos and stuccoed ceilings – 30 times the size of the Sistine Chapel!

All of this was built in only 4 years!

Why was it called the Domus Aurea?

If we imagine the same Roman sun of today with its warm hues illuminating the walls and ceilings covered with marble, intricate decorations, and gold leaf trimmings, it’s not hard to imagine how Domus Aurea (Golden House) earned its name. It must have been a spectacular sight.

Each of the rooms, including those for entertainment, dining, corridors, and courtyards were covered in frescoes and gold leaf.

So, why all the gold leaf? Well, according to sources of the time, after the Great Fire of Rome, Nero began to represent himself as the Sun God, going as far as to erect a 35-meter-high statue of himself portrayed as such. Since the house of the Sun God was golden, therefore to Nero’s house must be!

Here’s a fun fact: The giant statue of Nero was called Colossus Neronis, years later Emperor Hadrian placed it outside the Flavian Amphitheater. Due to the immense size of this nearby statue, ‘Neronis’ was dropped and with time and the Flavian Amphitheater became known as the ‘Colossus’ or ‘Colosseum’. So, in fact, the real name of the Colosseum is the Flavian Amphitheater!

Why was Domus Aurea built? Dispelling the myth that “Nero Fiddled while Rome burned”

Burning for six days, the Great Fire of Rome in 64AD caused widespread devastation on the night between 18 and 19 July.

Aristocratic dwellings on the slopes of the Palatine Hill in the heart of Ancient Rome were raised to the ground.

Legend has it that Nero was responsible for the fire, inspiring the expression “fiddling while Rome burns”. Meaning to occupy oneself with unimportant matters and neglect priorities during a crisis.

While it’s easy to cast the blame on Nero, who had ordered his wife and mother killed, had numerous enemies, and is remembered as one of history’s most sadistic and cruellest leaders, there still remains a few flaws with this story.

For one thing, the fiddle didn’t exist in ancient Rome. Music historians believe the viol class of instruments (to which the fiddle belongs) had not been developed until the 11th century! If anything, Nero would have played the cithara, a heavy wooden instrument with four to seven strings. However, there is still no solid evidence that he played one during the Great Fire.

This story may have stemmed from the Roman historian Tacitus who wrote that Nero was rumoured to have sung about the destruction of Troy while watching the city burn; however, he stated clearly that this was unconfirmed by eyewitness accounts.

Perhaps most importantly, when the Great Fire erupted, Nero was at his seaside villa at Antium, some 56 km (35 miles) from Rome. Upon hearing the news, Nero immediately returned and began relief measures, including opening his gardens and public buildings and importing grains from neighbouring towns.

Shortly after the fire, Emperor Nero took advantage of the situation and set about building a new decadent residence and fully landscaped portico villa for himself.

This didn’t sit well with the already mistrusting Romans, spurring on rumours that Nero had ordered the fire to be started just so he could build his Golden Palace and its surrounding gardens.

Nero blamed the Christians for the fire, which at the time was an obscure religious sect, and had many of them arrested and executed.

Convenient coincidence or not, the story of Nero fiddling while Rome burned is based on a popular legend instead of any established truth.

Why was it built in the centre of Rome?

While Emperor Hadrian built his equally large villa (in 2AD) some 22 kilometres from Rome near Tivoli, Nero built his right in the heart of the city. But, why?

Well, according to Prof. D’Alessio, (translated from Italian)

Nero identified himself with the city, because in a regime like that of Nero, it was fitting to take possession of the centre, the heart of the city. It was like saying “the city is mine”. There is an idea of privatisation of public spaces. In fact, what did the Emperors who followed do? They reinstated those spaces that were privatisation by Nero, back to the public. They then built the Flavian Amphitheatre, which is a building for spectators, shows, and for the people.

Why was the Domus Aurea buried and forgotten?

In 68AD Nero committed suicide, bringing to an end the rule of Julio-Claudian dynasty.

After Nero’s death, the Golden House was a massive embarrassment to his successors. Within a decade it was stripped of its marble, jewels, and ivory.

On the site of the lake, in the middle of the palace grounds, Vespasian built the Flavian Amphitheatre, with the Colossus Neronis beside it.

The palace and grounds, encompassing 2.6 km², were filled with earth and built over: the Baths of Titus were already being built on part of the site in 79 AD.

In 104AD, Emperor Trajan began building on top of the Domus Aurea, using it as the foundation for the largest Roman thermal baths ever built (today it’s still visible on the Oppian Hill).

Unfortunately, this meant the rooms of the Domus Aurea were both filled in with dirt and forever sealed off from the sun. To support the extensive baths, serious modifications were required which saw the construction of numerous additional walls.

Within 40 years, the Golden House was completely obliterated, buried beneath the new constructions. Paradoxically this ensured the wall paintings’ survival by protecting them from dampness.

With the Domus Aurea now underground, it was subsequently forgotten about.

How was the Domus Aurea rediscovered?

One day in the 15th century, a young Roman inadvertently fell through a cleft in the Esquiline hillside. He found himself in a strange cave or “grotta” filled with painted figures.

It didn’t take long for the young artists of Rome to flock to the area and have themselves lowered down into the rooms on boards knotted to ropes.

How did Domus Aurea influence the Renaissance?

The fourth style frescoes that were uncovered have since faded to pale grey stains on the plaster, but the effect of these freshly rediscovered grottesche decorations was electrifying in the early Renaissance, which was just arriving in Rome.

Pinturicchio, Raphael and Michelangelo were all lowered down shafts to study the frescoes and left their mark by carving their names on the walls. The paintings were a revelation of the true world of antiquity.

Shown here are two large openings through which artists of the Renaissance entered and the inspiration for future their paintings.

Besides the graffiti, signatures of later tourists, like Casanova and the Marquis de Sade scratched into a fresco inches apart, are the autographs of Domenico Ghirlandaio, Martin van Heemskerck, and Filippino Lippi.

The frescoes’ effect on Renaissance artists was instant and profound. The most obvious example is in Raphael’s decoration for the loggias in the Vatican.

Can I visit the Domus Aurea?

Absolutely! I highly recommend it. After 15 years of being closed, the Domus Aurea reopened to the public in 2014, albeit with very limited access. Open only on weekends, visitors are able to trace the footsteps of Nero with a fantastic guided tour lasting between 75-90 minutes.

Tours are available in English, Italian, and Spanish. Tickets are sold only online and go pretty fast so plan well and purchase your tickets well in advance. 

During my three years of living in Rome the Domus Aurea was still closed, so when I found out it had reopened I jumped at the chance to take a look inside. It’s truly an unforgettable experience. The tour groups are small which means you’re able to really appreciate the surroundings as take it all in.

What problems does the Domus Aurea Face?

One of the problems facing the Domus Aurea is the importance of maintaining the sensitive climate imposed since the construction of the thermal baths. Inside, the temperature drops to 12 degrees celsius while the humidity hovers around 90%.

Exposure to light causing photosynthesis has encouraged the growth of algae and other microorganisms, which in turn threaten the already fragile frescoes.

Another growing concern occurs on the surface. The roots of pine trees planted during the Fascist era have caused serious structural damage to the ceilings of Domus Aurea directly below them.

Perhaps the most problematic roots are those which are directly above the only remaining ceiling mosaic inside the Domus Aurea.

This delicate mosaic depicting Polyphemus and Nimfeo hovers above an elaborate water feature.

The roots of the pine tree above are so long they have even reached into adjacent rooms, weaving themselves into the structure of the ceiling. The removal of the tree is an extremely delicate task as there is a great risk the ceiling might collapse.

Light sources are kept to a minimal to avoid photosynthesis which can be seen near the floor lights.

How can I help save Domus Aurea?

There are many problems the Domus Aurea faces, but without sufficient funding its future is bleak. Some €35 million are needed.

Unfortunately, the government isn’t able to provide such an amount. Currently, hopes are pinned on finding a private investor. This wouldn’t be the first time that a Roman monument received private support.

Thanks to Italian tax breaks, the luxury shoe company Tod’s spent €25 million cleaning the Colosseum, Bulgari followed suit with spending €1.5 million the Spanish Steps, and Fendi threw €2.5 million euros into the Trevi Fountain. Thanks to these investments, Rome’s monuments have received the much-deserved care they needed and are looking pretty amazing. Let’s hope Domus Aurea will be another success story.

So, while you probably don’t have a spare €35 million, you can show your support by purchasing a ticket for a guided tour, and donate via Crowdfunding. Remember, every bit counts! You can even follow its progress, so you know exactly where your money is going. Very cool!

A big thanks to Professor Alessandro D’Alessio (Scientific Director of the Domus Aurea) for making this article possible.
