House of the Centenary IX-8, 6

The House of the Centenary IX-8, 6 is one of Pompeii’s largest and most complex private residences. Standing on Via di Nola, it occupies a substantial part of Insula 8 in Regio IX and is organised around two atria, a large peristyle, reception rooms, a private bath suite, service areas and gardens with water features.

Its modern name commemorates its discovery in 1879, the eighteenth centenary of the eruption of AD 79. The building was long described as a large domus erected in the second century BC and later remodelled. Research undertaken by the Vesuviana project has revealed a much more complex history: at least three residential units already occupied this part of the insula between the late fourth and early third centuries BC. They were gradually altered and combined, eventually forming the great monumental residence of the Augustan period.

A house formed by combining several dwellings

The House of the Centenary was therefore not constructed to a single design. Its irregular plan preserves traces of several earlier buildings that were extended, altered and progressively incorporated into one property over the centuries. This process explains the two atria and the architecturally distinct sections of the house.

The decisive phase came in the Augustan period, when the great domus with two atria and a vast peristyle took shape. The property then achieved a monumentality comparable to that of the city’s leading aristocratic residences. Alterations continued throughout the first century AD, however, and the functions of some sections changed profoundly after the earthquake of AD 62.

The two atria

The two atria are among the clearest signs of the building’s gradual development. The principal core retained the traditional organisation of a Roman domus, with entrance, atrium, side rooms and tablinum, while a second section had its own atrium and an independent arrangement of spaces.

This multiplication of rooms allowed different activities to be separated within the same property. A large household could maintain distinct areas for reception, private life, domestic service and economic activity instead of concentrating everything around a single domestic centre.

The peristyle

The large peristyle was the main monumental focus of the house. Porticoes surrounded the garden and linked triclinia, sitting rooms and other spaces used for the most prestigious aspects of domestic life. Water, planting and decoration created an environment devoted to otium and the reception of guests.

A basin and systems of fountains stood in and around the peristyle, with a nymphaeum at the far end. The ensemble would originally have been far more theatrical than it appears today: columns, plants, moving water and painted walls formed a single domestic landscape designed to impress those admitted to the residence’s more private areas.

The nymphaeum

The nymphaeum belongs to the complex’s later alterations. It was conceived as a monumental structure in which water flowed through architectural and decorative elements before collecting in the basin below. Its decoration included motifs from the aquatic world, while naturalistic scenes appeared on the surrounding walls.

Fountains and nymphaea were highly prized in the large Pompeian houses of the first century AD, particularly after the aqueduct gave wealthy properties access to more water than cisterns alone could supply. At the House of the Centenary, water was therefore not merely practical but played a direct part in the display of domestic luxury.

The private baths

The residence also had a complete private bath suite, a privilege reserved for households able to maintain heating and water-supply systems within their own homes. The suite contained the characteristic rooms of the Roman bathing sequence: apodyterium, frigidarium, tepidarium and calidarium.

The frigidarium contained a cold-water pool, while the tepidarium and calidarium allowed bathers to pass gradually into heated rooms. On a domestic scale, the arrangement thus followed the model of the city’s large public baths. A facility of this standard within a private residence was a conspicuous sign of its owners’ wealth.

A richly decorated house

The building’s numerous construction phases were matched by repeated changes to its decoration. Mosaic floors, paintings and wall revetments belonged to different moments in the house’s long history and record the continual updating of rooms to suit their owners’ tastes.

Research has also identified paintings from the transition between the Third and Fourth Styles, confirming that the house continued to receive rich decoration in the final decades before the eruption. Not all the frescoes remain legible in situ: some were removed after the discovery and transferred to the National Archaeological Museum of Naples, while other surfaces have deteriorated through exposure since excavation.

Bacchus and Vesuvius

One of the most important images for our understanding of the ancient Vesuvian landscape comes from the House of the Centenary: the celebrated fresco generally known as Bacchus and Vesuvius, now in the National Archaeological Museum of Naples.

The painting shows Dionysus-Bacchus beside a great mountain covered in vegetation and rows of vines, traditionally identified as Vesuvius before the eruption of AD 79. Its profile differs markedly from the mountain today because the Plinian eruption profoundly altered the summit.

The image is also significant for the relationship it establishes between Dionysus and the Vesuvian region. The god was closely associated with vines and wine, and the slopes of Vesuvius were already intensively cultivated in antiquity. The painting therefore brings together the real landscape, agricultural fertility and religious imagery.

Vesuvius before the eruption

The fresco should not be read as a modern topographical view produced according to scientific principles, but it remains exceptional evidence of how the inhabitants of the area represented their landscape before the catastrophe.

The Archaeological Park itself uses this image to illustrate the profile of the Somma-Vesuvius complex before the eruption of AD 79. The mountain appears covered in vegetation, consistent with literary and archaeological evidence for an intensively cultivated territory.

The painting therefore reminds us that for Pompeii’s inhabitants, Vesuvius was first and foremost part of a fertile agricultural landscape: vineyards, villas and productive estates occupied its slopes for many centuries before the volcano became universally associated with the city’s destruction.

Dionysus and the culture of wine

The link with Dionysus was particularly appropriate in Pompeian society. Wine was one of the Vesuvian region’s most important products and was traded far beyond Campania. Amphorae from the Pompeian area have been found in many parts of the western Mediterranean.

In great residences, wine carried economic, social and religious value at the same time. It was an agricultural product, a traded commodity and central to the banquet, while Dionysus embodied its divine dimension. This explains the god’s frequent appearance in the paintings, mosaics and sculpture of Pompeian houses.

The erotic decoration

A secluded room in the House of the Centenary also retained paintings with erotic subjects. Their presence has prompted widely differing interpretations of the room’s function, some of which have proposed that it was used specifically for sexual activity.

Caution is advisable, however. Erotic imagery was widespread in Roman art and could appear in many kinds of domestic setting; the paintings alone cannot establish with certainty what took place in the room. The secure archaeological evidence is therefore limited to a small room decorated with erotic scenes, while more precise interpretations must remain hypothetical.

The service areas

Alongside the reception rooms was an extensive service area, with a kitchen, latrine, workrooms and spaces arranged around an additional atrium. Part of this zone had entrances independent of the main route through the residence.

This distinction matters because a house of this size could not function through the efforts of its owners’ family alone. Numerous people were needed to prepare food, maintain the rooms, procure supplies, clean and manage the property from day to day. Many were enslaved or otherwise held in servile status, and their presence is essential to any real understanding of how a large aristocratic domus operated.

A property transformed after the earthquake

The earthquake of AD 62 marked a decisive break in the history of the House of the Centenary. Research by the Vesuviana project has shown that the functions of several areas changed substantially after the earthquake and that some formerly residential spaces were adapted to more practical and profitable uses.

This evidence alters the traditional image of the house as a great residence that remained essentially unchanged until AD 79. During Pompeii’s final seventeen years, the property was instead undergoing economic and functional reorganisation.

The purpose of every individual room cannot be defined without considering its successive building phases, but the overall picture is clear: the aristocratic house of the Augustan period was progressively adapted to the property’s changing needs.

Pompeii after the earthquake

The transformation of the House of the Centenary formed part of a wider phenomenon. After the earthquake, many Pompeian buildings were repaired, enlarged, subdivided or assigned new activities. Some families invested heavily in their residences, while in other cases former domestic spaces acquired commercial or productive functions.

Pompeii in AD 79 was not a static city simply awaiting destruction. It was changing rapidly, as property, economic activity and architecture continued to evolve. The House of the Centenary is one of the most revealing places in which to observe this process.

Who owned the House of the Centenary?

The identity of the owner in AD 79 cannot be established with complete certainty. On the basis of graffiti and electoral inscriptions found in the area, scholars have associated the house with Aulus Rustius Verus and Tiberius Claudius Verus, both figures in Pompeii’s municipal political life.

These associations are important but do not constitute conclusive proof of ownership. Electoral inscriptions on façades document political and social relationships and may suggest the presence of particular families nearby, but they are not equivalent to deeds of title.

It is therefore more accurate to retain the conventional modern name House of the Centenary without assigning the building with certainty to any one person.

A house and a long urban history

Modern research has shown that the true importance of the House of the Centenary lies not only in its size or in the works of art found within it. The building preserves a genuine sequence of Pompeii’s urban history, from the first dwellings of the fourth and third centuries BC, through the great Augustan transformation, to the reorganisation of its spaces after the earthquake of AD 62.

The existence of at least three original properties, later joined together, shows how a large residence could develop over generations through the acquisition and transformation of neighbouring buildings. The house is thus a source not only for the history of domestic architecture, but also for the history of property and urban society.

The excavations of 1879

Excavation of the house began in 1879, the year in which eighteen centuries since the eruption were commemorated. This event gave rise to the name House of the Centenary, which therefore has no connection with the identity of its ancient occupants.

Investigations continued in subsequent years and gradually uncovered the vast complex. As was customary in nineteenth-century excavations, several paintings and works regarded as particularly valuable were removed and transferred to the National Archaeological Museum of Naples.

To understand the house’s original richness today, its archaeological spaces must therefore be considered together with the works now held by the museum.

Research by the Vesuviana project

The House of the Centenary was later selected as one of the principal case studies of the Vesuviana project, developed in collaboration with the Archaeological Park of Pompeii and the University of Bologna.

A review of historical documentation, a survey of the structures and the integration of evidence in digital systems have enabled researchers to reconstruct the property’s successive phases far more clearly. These investigations overturned the older picture of a house simply built in the second century BC, identifying occupation of the area between the late fourth and early third centuries BC and the subsequent formation of the great domus in the Augustan period.

The House of the Centenary is therefore also an excellent example of how modern research can substantially revise archaeological interpretations repeated in guidebooks for decades.

One of Pompeii’s great houses

The House of the Centenary IX-8, 6 is fundamental to understanding the development of Pompeian society. Its two atria and vast peristyle reflect the expansion of a large property; the nymphaeum and private baths attest to an exceptional level of comfort; paintings and mosaics reveal its occupants’ culture and taste, while the service areas show the labour required to maintain a residence of this scale.

The famous fresco of Bacchus with the mountain traditionally identified as Vesuvius also links the house directly to the landscape surrounding Pompeii before the eruption. Yet perhaps the most interesting insight comes from recent research: what appeared in AD 79 to be a single great residence was actually the result of more than three centuries of acquisition, expansion, decoration and changing use.

The House of the Centenary is therefore more than one of Pompeii’s largest houses. Its successive layers reveal the transformation of the city from the Samnite period to the early Empire and into the final years before the eruption.
