Founded	c. 64–68 AD

The Domus Aurea (Latin, "Golden House") was a vast landscaped complex built by the Emperor Nero largely on the Oppian Hill in the heart of ancient Rome after the great fire in 64 AD had destroyed a large part of the city.^[1]

It replaced and extended his Domus Transitoria that he had built as his first palace complex on the site.^[2][3]

History

The Domus Aurea was probably never completed.^[4] Otho^[5] and possibly Titus allotted money to finish at least the structure on the Oppian Hill; this continued to be inhabited, notably by emperor Vitellius in 69 but only after falling ill,^[6] until it was destroyed in a fire under Trajan in 104.^[7]

It was a severe embarrassment to Nero's successors as a symbol of decadence and it was stripped of its marble, jewels, and ivory within a decade.^[8] Although the Oppian villa continued to be inhabited for some years, soon after Nero's death other parts of the palace and grounds, encompassing 2.6 km² (c. 1 mi²), were filled with earth and built over: the Baths of Titus were already being built on part of the site, probably the private baths, in 79 AD.^[9][10] On the site of the lake, in the middle of the palace grounds, Vespasian built the Flavian Amphitheatre, which could be flooded at will,^[11] with the Colossus of Nero beside it.^[1] The Baths of Trajan,^[1][12] and the Temple of Venus and Roma were also built on the site. Within 40 years, the palace was obliterated. Paradoxically, this ensured the wall paintings' survival by protecting them from moisture.^[13][9][14]

Rediscovery

When a young Roman inadvertently fell through a cleft in the Esquiline hillside at the end of the 15th century, he found himself in a strange cave or grotto filled with painted figures.^[8] Soon the young artists of Rome were having themselves let down on boards knotted to ropes to see for themselves.^[15] The Fourth Style frescoes that were uncovered then have faded now, but the effect of these freshly rediscovered grotesque^[16] decorations (Italian: grotteschi) was electrifying in the early Renaissance, which was just arriving in Rome.

When Raphael and Michelangelo crawled underground and were let down shafts to study them, the paintings were a revelation of the true world of antiquity.^[17] Beside the graffiti signatures of later tourists, like Casanova and the Marquis de Sade scratched into a fresco inches apart (British Archaeology June 1999),^[18] are the autographs of Domenico Ghirlandaio, Martin van Heemskerck, and Filippino Lippi.^[19]

It was even claimed that various classical artworks found at this time, such as the Laocoön and His Sons and Venus Callipyge,^[20] were found within or near the Domus's remains, though this is now accepted as unlikely (high quality artworks would have been removed to the Temple of Peace before the Domus was covered over with earth).^[20]

The frescoes' effect on Renaissance artists was instant and profound (it can be seen most obviously in Raphael's decoration for the loggias in the Vatican), and the white walls, delicate swags, and bands of frieze—framed reserves containing figures or landscapes—have returned at intervals ever since, notably in late 18th century Neoclassicism,^[21] making Famulus one of the most influential painters in the history of art.

20th century to present

Discovery of the pavilion led to the arrival of moisture starting the slow, inevitable process of decay; humidity sometimes reaches 90% inside the Domus.^[17] Heavy rain was blamed for the collapse of a chunk of ceiling.^[22] The presence of trees in the park above is causing further damage, as tree roots are slowly sinking into the walls, damaging the ceiling and frescoes; chemical compounds released from these roots are provoking additional deterioration.^[23][10] Many of these trees cannot be uprooted without damaging the Domus.^[24]

The sheer weight of earth on the Domus is causing a problem, as well, and architects believe that the ceiling will eventually collapse if the weight of between 2,500 and 3,000 kg/m² is not lessened.^[9] A pilot project is in the works to replace the current park above the Domus, enlarged during Mussolini's regime,^[25] with a lighter roof garden planted with the type of flowers described by Pliny, Columella, and other ancient writers.^[9]

Increasing concerns about the condition of the building and the safety of visitors resulted in its closing at the end of 2005 for further restoration work.^[26] The complex was partially reopened on February 6, 2007, but closed on March 25, 2008 because of safety concerns.^[27][17]

On March 30, 2010, 60 square metres (650 square feet) of the vault of a gallery collapsed.^[14]
