The public buildings of Pompeii and Herculaneum, including the Forum and its surrounding temples, basilica, macellum and Eumachia building, the public baths (Stabian, Forum, the unfinished Central Baths, and the Suburban Baths at Herculaneum), the amphitheatre of c. 70 BC, the theatres and the palaestra, and the private buildings, including the atrium-peristyle domus (e.g. the House of the Faun and the House of the Vettii), insulae and upper-floor apartments, and the Villa of the Mysteries and Villa of Papyri, and what they reveal about urban life

What this dot point is asking

NESA expects you to describe the public buildings that structured civic, religious, commercial and leisure life (the Forum precinct, the baths, the amphitheatre, the theatres and the palaestra) and the private buildings that housed Pompeians and Herculaneans across the social scale (the atrium-peristyle domus, insulae and rented upper floors, and the two great suburban villas), and to argue what this built environment reveals about urban life: status, benefaction, leisure culture and the gap between rich and poor. Strong answers name specific buildings, dates and patrons rather than describing "Roman architecture" in general.

The answer

The Forum: the civic, religious and commercial heart

Pompeii's Forum was a long, rectangular, colonnaded piazza closed to wheeled traffic (stone bollards still mark the entrances) at the south-western end of the walled city. It was the physical stage for everything the dot point on local political life covers (elections, the decurional council, public notices) and for state religion, but it was also ringed by buildings with distinct civic, religious and commercial functions in their own right.

At the north end stood the Capitolium (Temple of Jupiter, also housing Juno and Minerva as the Capitoline Triad), dominating the view down the length of the piazza; it was badly damaged in the AD 62 earthquake and still under repair in AD 79. On the west side stood the Temple of Apollo, the oldest cult site on the Forum, with visible Greek and Samnite-period origins predating Roman colonisation.

The basilica, the macellum and the Eumachia building

At the south-west corner stood the Basilica, Pompeii's largest roofed building (probably built in the late 2nd century BC, making it one of the earliest identifiable basilicas anywhere in Italy). It combined the functions of a law court and a covered exchange for business, with a raised tribunal at one end for magistrates.

On the north-east corner stood the macellum, the covered meat and fish market. Excavation has recovered fish scales and animal bone in its drains, confirming its trading function; at its centre stood a tholos, a small circular structure (most likely a fountain or a fish tank) that gave the market a recognisable civic form rather than a mere row of stalls.

On the east side, between the Sanctuary of the Public Lares and the small, unfinished Temple of Vespasian, stood the Eumachia building: a large hall behind an elaborate porticoed facade, funded by the public priestess Eumachia (whose father had been a duumvir) and dedicated, according to its surviving inscription, to Concordia Augusta and Pietas, values closely tied to the imperial family. The building has traditionally been associated with Pompeii's fullers (wool-cleaners) as a guild headquarters, though this identification is now debated among historians rather than certain. Whatever its precise trade function, the Eumachia building is unmistakable evidence of a wealthy woman using monumental public architecture, alongside the Forum's temples, to convert private wealth into lasting civic prestige.

Public bathing: the four bath complexes

Bathing was one of the most important shared leisure activities in Pompeii and Herculaneum, and the surviving complexes show the practice evolving across two and a half centuries. The Stabian Baths, with origins in the 2nd century BC, are the oldest and largest, built around a spacious palaestra (exercise yard) with separate suites for men and women, each running frigidarium (cold room) to tepidarium (warm room) to caldarium (hot room) over an underfloor hypocaust heating system.

The Forum Baths, built soon after Pompeii became a Roman colony in 80 BC, are smaller and more architecturally refined, with a finely stuccoed, coffered ceiling surviving in the men's tepidarium. The Central Baths, begun after the AD 62 earthquake, were still unfinished when Vesuvius erupted in AD 79; their single continuous suite (no separate male/female wings) and much larger windows show a newer, later Roman approach to bathing that Pompeii never got to complete. At Herculaneum, the Suburban Baths sat just outside the town wall near the ancient shoreline, with unusually large windows opening onto the sea and a well-preserved private latrine, reflecting the town's smaller, more residential and less commercially driven character.

Entertainment architecture: theatres, amphitheatre and palaestra

The Theatre Quarter combined the Large Theatre (Hellenistic in origin, rebuilt in Roman form under the patronage of the Holconius family and seating around 5,000) with the smaller, roofed Odeon (seating roughly 1,500) used for music, recitation and mime, and the Quadriporticus (originally a portico for theatre-goers, later converted into gladiator barracks).

The amphitheatre, built around 70 BC by the duoviri Gaius Quinctius Valgus and Marcus Porcius, is the earliest surviving stone amphitheatre anywhere in the Roman world. Rather than the free-standing tiered arcades of Rome's later Colosseum, it was built into a raised earth embankment, an economical solution reached barely a decade after Pompeii's colonisation, seating around 20,000, more people than the town's own free population. A fresco from the House of Actius Anicetus depicts the violent AD 59 riot there between Pompeians and visiting Nucerians, an event also recorded by Tacitus (Annals 14.17), who notes the Senate's resulting ten-year ban on gladiatorial games at the town.

A large colonnaded palaestra (an open exercise ground, distinct from the smaller Samnite Palaestra) stood near the amphitheatre and, according to inscriptions, was associated with the town's organised youth (a collegium iuvenum), showing that physical training and civic identity for young free men were built into Pompeii's urban plan alongside religion, law and trade.

Private architecture: the atrium-peristyle domus

The classic elite house at Pompeii combined a public-facing reception sequence (the fauces entrance corridor, the atrium with its rainwater-catching impluvium and compluvium, and the tablinum, the owner's office positioned so visitors could see straight through the house from the street) with a private rear courtyard, the peristyle, a colonnaded garden that typically held dining rooms (triclinia) and additional bedrooms (cubicula).

The House of the Faun, at roughly 3,000 square metres the largest private residence at Pompeii, took this plan to an almost palatial scale, with two atria and two peristyles, the bronze statuette of the Dancing Faun (giving the house its name) in its first impluvium, and the Alexander Mosaic (depicting Alexander the Great in battle) in a room off the second peristyle. It dates originally to the Samnite period (2nd century BC), showing that Pompeii's elite were building on this scale before the town even became a Roman colony.

The House of the Vettii, by contrast, belonged to two freedmen brothers, Aulus Vettius Restitutus and Aulus Vettius Conviva, whose wealth (probably made in trade) bought them an elaborate Fourth Style redecoration after the AD 62 earthquake but not, since freedmen could not hold magistracies, a tablinum used for legal business in the traditional sense. Andrew Wallace-Hadrill uses the Vettii house to argue that Roman domestic architecture is not a fixed social script: freedmen wealth could out-decorate old elite houses even while remaining formally excluded from the political roles those houses traditionally displayed.

Non-elite housing: insulae and upper-floor apartments

Most residents of Pompeii and Herculaneum did not live in a domus at all. Multi-storey blocks known as insulae combined ground-floor shops (tabernae), often with a small mezzanine or back room for the shopkeeper's family, and separate upper-storey rooms (cenacula) rented out independently. A painted notice advertising space in the Insula Arriana Polliana, owned by Gnaeus Alleius Nigidius Maius, offered shops with their upper rooms and additional lodgings for lease on a five-year term, with enquiries directed to the owner's slave, direct evidence of an organised rental business run for profit by a single wealthy landowner.

Most of Pompeii's upper floors collapsed either in the AD 62 earthquake or in the AD 79 eruption itself, so the clearest physical evidence for this kind of housing survives at Herculaneum, where the pyroclastic surge charred rather than destroyed timber. The Trellis House and the House of the Wooden Partition preserve carbonised wooden-framed upper storeys, in the Trellis House's case with a wooden balcony (maenianum) projecting out over the street, showing cramped rented lodgings stacked directly above street-level workshops, often within the same building, or even the same ownership, as a grand domus nearby.

The suburban villas: the Villa of the Mysteries and the Villa of Papyri

Just outside the Porta Ercolano, the Villa of the Mysteries combined an elite residence with active wine production (a torcularium, or wine press, survives on site). Its renown rests on the megalography frieze in one triclinium: a near life-size sequence of figures painted in the Second (Architectural) Style, generally interpreted as depicting rites connected with the cult of Dionysus/Bacchus, making the villa a rare survival of large-scale elite religious/mythological art outside a public temple.

At Herculaneum, the Villa of Papyri was a vast, multi-terraced seaside residence, traditionally though not certainly associated with the family of Lucius Calpurnius Piso Caesoninus (Julius Caesar's father-in-law). Excavated mainly by tunnelling in the 1750s under the engineer Karl Weber, it yielded a library of around 1,800 carbonised papyrus scrolls, overwhelmingly the philosophical writings of the Epicurean Philodemus of Gadara, the only substantially intact library to survive from the ancient world. The villa's design directly inspired the reconstructed J. Paul Getty Museum building in Malibu, California (opened 1974). Since 2023, an international effort using CT scanning and machine-learning image analysis (the "Vesuvius Challenge") has begun virtually unrolling and reading some of these still-unopened scrolls without physically damaging them, a genuinely live area of the evidence base.

Public and private buildings at a glance

How to read a source on this topic

Section I sources on buildings typically include photographs or plans of the Forum, house facades, bath interiors, the amphitheatre, or extracts describing a villa. Three reading habits.

First, separate function from status. A building's function (market, bath, house) is only half the evidence; ask who paid for it, who used it, and what that combination reveals. The Eumachia building's dedication tells you about Eumachia's status as much as about wool-working.

Second, distinguish elite from non-elite evidence explicitly. The House of the Faun and the Villa of Papyri are spectacular but atypical; the Insula Arriana Polliana rental notice and Herculaneum's carbonised upper floors are rarer but more representative of how most residents lived. A high-band answer states which kind of evidence a source gives.

Third, note what survived and why. Herculaneum's pyroclastic surge preserved timber and organic material that Pompeii's fall of ash and pumice destroyed, so silence in Pompeii's record (on upper floors, for instance) is not evidence of absence.

Historians on the buildings of Pompeii and Herculaneum

Paul Zanker (Pompeii: Public and Private Life, 1998) reads the public and private buildings together as one coordinated statement of civic and personal status: the same elite families who funded the Forum's temples and halls also redecorated their own houses, so public benefaction and private display reinforced each other rather than belonging to separate spheres. Andrew Wallace-Hadrill (Houses and Society in Pompeii and Herculaneum, 1994) demonstrates that Roman houses, elite or otherwise, routinely mixed production, commerce and modest lodging with formal reception space, undermining any tidy modern line between "public" and "private" architecture. Mary Beard (Pompeii, 2008) stresses that famous buildings such as the House of the Faun and the Villa of the Mysteries are unrepresentative outliers, and that the insulae and rented upper rooms, though far less visited and far less photographed, housed the majority of the population. Alison Cooley (Pompeii and Herculaneum: A Sourcebook, 2014) provides the standard translations of the building inscriptions (the Eumachia dedication, the amphitheatre benefaction) used to date and attribute these structures.
