Among Algeria’s Roman ruins, two sites stand apart as among the most remarkable in the entire Mediterranean world: Timgad, the colonial city nicknamed the “Pompeii of North Africa”, and Djemila, the ancient Cuicul perched in the mountains of Petite Kabylie. Both inscribed on the UNESCO World Heritage List since 1982, they together offer an unparalleled panorama of Roman urban genius in North Africa. This complete guide will help you plan your visit.

Why Visit Algeria’s Roman Ruins?
Algeria is one of the best-endowed countries in the Mediterranean basin for Roman archaeological sites — and yet one of the least visited. That is precisely the advantage: Timgad and Djemila can be explored without crowds, in a silence rare for sites of this importance. You walk through ancient cities spanning several dozen hectares — forum, theatre, baths, library, triumphal arch — with no companion but millennia-old stones and, occasionally, a local guide who knows every column.
These two cities also illustrate two complementary aspects of Roman urbanism: the geometric rigour of the grid plan at Timgad, and the adaptation to mountainous terrain at Djemila. Two ways of being Roman, two landscapes, one shared ambition of civilisation.
Timgad, Algeria: The Best-Preserved Roman Colony in the World
What Is Timgad?
Timgad (or Thamugadi), nicknamed the “Pompeii of North Africa”, is an ancient city founded in 100 AD by Emperor Trajan on the northern slopes of the Aurès massif, in the present-day wilaya of Batna. Its full name is Colonia Marciana Traiana Thamugadi: Marciana is the name of Trajan’s sister, Thamugadi the Berber name for the site.
Created ex nihilo — literally from nothing — as a military colony for veterans of the Third Augustan Legion, the city still presents today an orthogonal plan of startling clarity, commanded by the cardo maximus (north-south axis) and the decumanus maximus (east-west axis). This perfect grid, drawn up by Roman engineers, makes Timgad one of the most complete and best-preserved examples of Roman urban planning in the world.
Initially covering 12 hectares, the city gradually expanded to over 90 hectares at its height under the Severan dynasty (late 2nd – early 3rd century), when it housed around 15,000 inhabitants. It was inscribed on the UNESCO list in 1982 (criteria ii, iii, iv).
What to See at Timgad
The Forum
The central hub of all civic life, Timgad’s forum is a vast paved square measuring 50 × 43 metres, surrounded by Corinthian-columned porticoes. It once housed the curia (local senate), a civil basilica and a temple. On one step of the forum, an engraved inscription neatly summarises its inhabitants’ philosophy: Venari, lavari, ludere, ridere, occ est vivere — “To hunt, to bathe, to play, to laugh — that is living!”
The Theatre
Carved into a hillside south of the forum, Timgad’s theatre was built around 160 AD and could seat 3,500 spectators across 24 tiers of seats. It is still used for performances today.
The Arch of Trajan
The best-preserved monument on the site. Erected in the late 2nd century, this triple-bayed triumphal arch marks the city’s western exit towards Lambaesis. It is Timgad’s iconic photographic symbol.
The Library
One of only two public libraries from Roman antiquity ever found anywhere in the world, alongside that at Ephesus (Turkey). Reached by a five-step staircase, it was arranged around a porticoed courtyard whose walls were faced with blue and green marble. A white-marble-columned niche once housed a statue of Minerva.
The Capitol
The largest monument at Timgad, recognisable by its two majestic columns, located in the western suburbs. Its temple stood on a platform reached by a 38-step staircase, with a facade of 12 Corinthian-capital columns.
The Baths
Timgad had no fewer than 14 public bath-houses — an exceptional number for a city of its size, reflecting the central role of bathing in Roman social life.
The Cardo Maximus
A great avenue paved in blue limestone slabs, lined with colonnaded porticoes sheltering passers-by from sun and rain. The ruts carved by four centuries of cart traffic are still visible today.
The Timgad Museum
Built in 1930 at the entrance to the site, it houses one of the finest collections of Roman mosaics in Algeria, featuring geometric, floral and mythological designs produced in local workshops at the beginning of the 3rd century. Byzantine mosaics dated between the 4th and 6th centuries round out the collection.

Djemila, Algeria: The Mountain Roman City
What Is Djemila?
Djemila — its Arabic name means “the beautiful” — is the ancient Roman city of Cuicul, perched at 900 metres above sea level in the mountains of Petite Kabylie, approximately 50 km north-east of Sétif in the wilaya of the same name. Founded at the end of the 1st century AD, probably under the reign of Nerva or Trajan, the Roman colony was strategically placed on a rocky spur ringed by ravines — a naturally defensive and near-impregnable site.
What makes Djemila utterly unique in the Roman world is the remarkable way its urban plan adapts to a turbulent mountain relief. Unlike Timgad’s perfect grid, Djemila takes on an approximately triangular form that follows the contours of the ridge, with gently sloping streets and public spaces cleverly arranged in successive terraces. UNESCO describes it as “a remarkable example of Roman urban planning adapted to a mountainous site”. It was inscribed on the World Heritage List in 1982 (criteria iii, iv).
What to See at Djemila
The Roman Forum and the Old Forum
The original city is organised around a first rectangular forum with its cardo and decumanus. As the population grew, a second monumental complex — the Severan Forum — was built further south.
The Temple of the Severan Family
Built around 229 AD, it is the best-preserved temple on the site. A monumental staircase leads to a vast colonnaded platform, then a portico flanked by six columns ten metres high. The colossal heads of imperial statues found during excavations are displayed in the museum.
The Triumphal Arch of Caracalla
Erected in 216 AD by the municipality of Cuicul in honour of Emperor Caracalla, his mother Julia Domna and his father Septimius Severus, this single-bayed monumental arch measures 12.5 metres high and 11.6 metres wide. It marks the entrance to the Severan Forum from the Sétif road. Its grey limestone has acquired a beautiful golden patina over time. In 1839, the Duc d’Orléans conceived a plan to transfer it to Paris as a companion piece to the Arc de Triomphe du Carrousel — a project fortunately abandoned.
The Theatre
Built against the hillside, Cuicul’s theatre could seat around 3,000 spectators. Partially restored, it retains remarkable acoustics. Its integration into the mountain landscape makes it one of the most beautiful ancient theatres in Africa.
The Baths of Caracalla
The city’s large public baths, with their perfectly identifiable hot and cold rooms, illustrate the importance of bathing in Cuicul’s social life.
The Christian Quarter
In the 4th century, the conversion to Christianity led to the construction of an episcopal quarter in the south of the city: a great basilica, a cathedral, and above all an octagonal domed baptistery whose ambulatory is hollowed with 36 niches. Considered among the most remarkable of the early Christian era, this baptistery is one of the jewels of the site.
The Djemila Museum
Located at the entrance to the park, it houses a collection of mosaics of universal quality, considered among the finest in Roman Africa. The Mosaic of the Seasons and Months and that of the Triumph of Bacchus are on display. Statues, capitals and inscriptions complete the visit in a lapidary garden.
Approximately 40 hectares of the ancient city’s 75 remain buried underground, awaiting future excavation.
