Volubilis: the Roman city of Morocco classified as UNESCO which defies the centuries

30 kilometers from Meknes, the in situ mosaics, the Arch of Caracalla and the oil presses of Volubilis tell two thousand years of Berber, Roman and Islamic history on a plateau in the Middle Atlas.

Volubilis Morocco: the ancient capital of Mauretania Tingitane, its in situ mosaics (Orpheus, Bacchus, Hercules), the Arch of Caracalla (217 AD) and its history from Juba II to Moulay Ismaïl. UNESCO 1997.

Imagine a March morning on the Zerhoun plateau, thirty kilometers north of Meknes. The storks have found their nests on the Corinthian capitals and the spring grasslands have invaded the ancient *cardines maximi* - the large rectilinear streets that the Roman surveyors traced here nineteen centuries ago. A few hundred meters further on, in what was once the house of a wealthy notable, a brown marble Orpheus plays the lyre to calm the wild beasts - a scene frozen in tesserae since the 2nd century AD, exposed to the same rains and the same skies of North Africa as at the time when it was placed. Welcome to Volubilis, the best preserved Roman city in Morocco, listed as a UNESCO World Heritage Site since 1997 and classified among the most important archaeological sites in all of Africa.

Volubilis before Rome: a Berber city with deep roots

The history of Volubilis — *Oualili* in Arabic, a name inherited from the Berber *Walili* which perhaps designates the oleander which still grows on its slopes — does not begin with Julius Caesar nor with Augustus. It began well before, from the 3rd century BC, when Berber populations settled on this fertile plateau between the Khoumane and Fertassa rivers, at an altitude of 400 meters on the southern flank of Jbel Zerhoun. Archaeological excavations carried out since 1915 have uncovered Neolithic and protohistoric levels of occupation, as well as vestiges of a structured Berber habitat predating any Roman presence. Volubilis is not a colonial creation: it is an indigenous city that Rome absorbed, enlarged and monumentalized.

The decisive turning point came in the 1st century BC with the annexation of Mauretania – the Berber kingdom which roughly covered what is now northern Morocco and western Algeria – to the Roman orbit. In 25 BCE, Augustus entrusted this client kingdom to *Juba II*, a Numidian Berber prince raised in Rome within the entourage of the imperial family, a man of encyclopedic culture who spoke Greek and Latin, wrote treatises on geography and botany, and married *Cleopatra Selene*, daughter of Cleopatra VII and Mark Antony — the heiress of the Ptolemies. This unlikely royal couple, half-African and half-Hellenistic, made Caesarea (present-day Cherchell in Algeria) their official capital but granted Volubilis the rank of important city, equipped with a wall, a forum and the first carved stone monuments. The city enters Mediterranean history.

Mauretania Tingitane: Volubilis provincial capital of the Roman Empire

In 44 AD, under Emperor Claudius, Mauretania was divided into two provinces: *Mauretania Caesarian* to the east and *Mauretania Tingitane* to the west, whose administrative capital was established at *Tingi* — present-day Tangier. Volubilis is not the official capital, but it is quickly becoming the most important city in the province in terms of population and economic activity. Its location on the Zerhoun plateau, at the junction of the Atlantic cereal plains and the mountainous foothills, makes it a strategic commercial node. The excavations revealed a city planned according to the canons of Roman town planning: a north-south *cardo maximus* approximately 500 meters long, an east-west *decumanus maximus*, a forum with judicial basilica and Capitol, public baths, an honorary arch, and around a hundred private houses, several of which yielded mosaics of exceptional quality.

The economy of Volubilis is based on three pillars. First of all, cereal agriculture - the plains of Gharb and Saïs which extend to the west and south provide the wheat which makes this region the granary of the African empire. Then breeding - sources from the region mention the export of wild beasts intended for the Roman arenas. And above all olive oil: excavations have uncovered around sixty oil presses in the city and its suburbs, making it one of the best documented olive production sites in the entire empire. Dolia (storage jars) of several hundred liters have been found in warehouses whose walls, made of opus incertum and terracotta bricks, still reach two meters in height.

The Arch of Caracalla and the apogee of the Roman city Volubilis

The triumphal arch which still stands at the northeast entrance to the forum is the most famous architectural piece of Volubilis. It was erected in 217 AD under the governor *Marcus Aurelius Sebastenus*, in honor of the emperor *Caracalla* and his mother *Julia Domna*. Its dedicatory inscription, partially preserved, celebrates Caracalla's edict of 212 — the *Constitutio Antoniniana* — which granted Roman citizenship to all free inhabitants of the empire, an act which included for the first time the populations of Mauretania Tingitana. The arch, made of local limestone, measures approximately 8 meters in height. Its sculpted decoration - foliage friezes, Corinthian capitals, weapon trophies - is partially preserved and was the subject of partial restoration by the Moroccan Historical Monuments Service in the 1930s-1950s.

The 2nd and the beginning of the 3rd century constitute the golden age of the city. The population is estimated between 10,000 and 20,000 inhabitants, a considerable figure for the time. The city's wealthy merchants and civil servants brought in mosaic artisans from Italy and Tunisia capable of decorating the floors of their homes with vast figurative compositions. It was during this period that the mosaics which made the site's worldwide reputation were created: the *House of Orpheus* (Orpheus surrounded by animals, Amphitrite on a merman's chariot), the *House of Venus* (Diane the huntress surprised in the bath, the kidnapping of Hylas), the *House of the Procession of Venus*, the *House of the Labors of Hercules* (the twelve labors in medallions circular), and the *House of Dionysus and the Four Seasons* whose mosaic of Bacchus crowned with vines is one of the finest in the Roman Maghreb.

In Volubilis, the mosaics are not in a museum — they are on the ground, in the exact spot where a craftsman placed them nineteen centuries ago, under the same North African sky.

The mosaics of Volubilis: masterpieces in situ under the African sky

What sets Volubilis apart from most other Roman archaeological sites in the world is that its most important mosaics have remained on site, *in situ*, in the houses where they were placed. We don't see them in an air-conditioned museum window: we see them on the ground, in the darkness of open houses, protected by modern thatched roofs which shelter them without hiding them. The texture of the tesserae, the work of the joints, the restored areas and the original areas come together with an honesty that museum reconstructions do not achieve. Walking on the *decumanus maximus* and entering the threshold of the House of Orpheus - whose wooden door has disappeared seventeen centuries ago but whose stone pillar still stands - produces a sensation of temporal continuity that few sites in the world can offer.

The mosaic of Orpheus, in the main room of the house which bears his name (located approximately 200 meters west of the forum), is undoubtedly the most photographed on the site. It measures approximately 5 meters by 3. In the center, Orpheus sits playing the lyre; around him, in concentric circles, the animals listen to him — a lion, an elephant, a bear, a hare, a panther, an eagle. The tesserae used for the plumages of birds and the coats of wild animals reach a remarkable density and finesse. On the other hand, certain parts of the background were restored in the 20th century with slightly larger and less precise tesserae — and the eye eventually learned to distinguish the layers of time in the colored stone.

The end of the Roman city and its subsequent lives

The organized Roman presence in Volubilis ended around 285 CE, when Emperor Diocletian decided to withdraw the legions from Mauretania Tingitana — a province too distant and too costly to defend against incursions from southern tribes. This military withdrawal does not result in the immediate abandonment of the city. Life continues, but in a different form: a Romanized population, speaking Latin and of Christian faith then quickly Islamized, occupies the houses and monuments which are slowly deteriorating. Recent excavations have highlighted a continuity of occupation until at least the 8th century. It is to the Idrissides - the first Islamic dynasty of Morocco, founded by Idriss Iᵉʳ in 788 - that the last phase of intense life of the site is attributed. *Moulay Idriss Zerhoun*, the holy city which crowns the neighboring summit 5 kilometers east of Volubilis, is in fact the capital of the Idrissids - and the ruins of the ancient Roman city form the *dar al-baida* (white city) mentioned in medieval Arab chronicles.

The final blow is twofold. In 1755, the Lisbon earthquake - whose waves spread as far as deep Morocco - brought down entire sections of masonry that fifteen centuries of neglect had weakened. But long before this earthquake, it was the reuse of Volubilis stones for major Meknassi projects which had already seriously damaged the built heritage. Thirty kilometers away, Moulay Ismaïl (1672-1727) had marble columns, Corinthian capitals and blocks of carved apparatus taken from the site to reuse in his palaces, mosques and monumental gates of Meknes. The most famous case is that of Bab Mansour, whose Corinthian columns flanking the central arch come directly from the forum of Volubilis — a movement of material which symbolically unites two empires separated by fifteen centuries.

Visiting Volubilis from Meknes: what you will see

• The Arch of Caracalla (217 AD): enter the site through the south ticket office and go up the decumanus towards the north-east to arrive facing the arch backlit in the late afternoon light
• The Capitol and the Judicial Basilica: the Capitol with its reconstructed Corinthian columns is visible from the entrance; the Basilica, behind, retains its apses and several Latin inscriptions in situ
• The House of Orpheus: about 200 meters west of the forum — the mosaic of Orpheus, that of Amphitrite and the nine dolphins of the triclinium are the most beautiful on the site
• The House of Labors of Hercules: the twelve labors in medallions around a central scene of Bacchus, 300 meters north of the Capitol
• The House of Venus: mosaics of Diana surprised in the bath and the kidnapping of Hylas — exceptional condition for the humidity of the color
• The oil presses: around twenty are visible in the north-eastern district of the site, with their basalt millstones and their storage dolia - the olive production of Volubilis probably supplied the entire province
• Moulay Idriss Zerhoun: the holy village visible 5 km to the east from the heights of the site deserves an additional half-day — free access to the village (access to the mosque-mausoleum reserved for Muslims)

Volubilis listed by UNESCO in 1997: why this site matters for world archeology

The inscription of Volubilis on the UNESCO World Heritage List in 1997 is based on two main criteria: its exceptional testimony to Roman culture in North Africa, and the remarkable state of conservation of its urban fabric - notably the mosaics in place, the presses, and the masonry elevations which still make it possible to read the structure of the city like a plan in relief. The UNESCO committee also highlighted the superposition of cultures – pre-Roman Berber, Roman, Christian, Islamic – which makes Volubilis a living document of two thousand years of North African civilization, beyond the Roman period alone which captures most of the attention of visitors.

Archaeological excavations, carried out since 1915 first by the Historical Monuments Service of the French Protectorate under the direction of Louis Chatelain, then resumed after independence by the Moroccan Ministry of Culture and international university teams, have only uncovered about half of the estimated total surface area of the ancient city. The other half still sleeps under the agricultural land which extends to the north and east of the classified area. Research carried out in recent years by Moroccan-French teams using non-invasive techniques (ground radar, drone photogrammetry) has begun to map these buried areas — with results that give hope for major discoveries in the coming decades.

Volubilis in 2026: a living site between heritage and tourism

The archaeological site of Volubilis covers 42 hectares according to UNESCO. A careful visit generally takes several hours, because the remains, mosaics and inscriptions are spread over a vast plateau with little shade. It is prudent to consult official prices and timetables before traveling, bring water and sun protection, and avoid the hottest hours in summer. The late afternoon light particularly highlights the sculpted reliefs and mosaics.

What Volubilis says about Morocco in 2026 is something that official history rarely emphasizes forcefully enough: Morocco is not a single-layer country. Its territory was successively Berber, Phoenician, Carthaginian, Roman, Christian, Islamic, Arab-Andalusian, Berber again, Alawite - and these strata do not erase each other, they accumulate and interact. The Corinthian columns of Volubilis which are found at Bab Mansour thirty kilometers away are not a pillage: they are a conversation. Between an empire that faded away and a sultanate that remembered it to claim its heritage. Walking in the ruins of the Roman city Volubilis means understanding that Morocco has always known how to recycle its past to build its present - and that this is perhaps its most profound way of being a civilization.
