Timgad is one of the great archaeological treasures of Africa and the Roman world. It's an entire city that Emperor Trajan founded from scratch around 100 AD, laid out like a chessboard, with perfectly straight streets meeting at right angles. When you stand by Trajan's Arch and look at the grid of paved streets spreading across the plain, you suddenly understand how the Romans thought and built.
Its nickname, 'the Pompeii of Africa', is no exaggeration. Buried under Saharan sand for more than a thousand years, Timgad survived in exceptional condition, with its forum, a theatre that held thousands of spectators, baths, a library (a rarity) and dozens of streets and houses. It's the most complete and instructive example of Roman town planning in a military colony that exists anywhere, an open-air history textbook.
This guide helps you get the most out of a visit to Timgad. It covers what to see on the site, how to explore its layout, what the mosaic museum holds, how much admission costs and how to get there from Batna or Constantine. Together with nearby Djémila, it makes up the pair of Roman gems in northeastern Algeria: two World Heritage Sites that are worth the trip on their own.
Emperor Trajan founded Timgad around 100 AD as Colonia Marciana Traiana Thamugadi, a settlement for veterans of the Legio III Augusta on the Empire's southern frontier. It was designed from scratch on a perfect grid plan and thrived for centuries, first as a Roman city and later as a Christian one, until it was sacked and abandoned after the invasions. Sand buried and preserved it until it was excavated in modern times. The full story is on the history page.

Origins, formation and what the sources say.
Unlike most ancient cities, which grew little by little out of villages, Timgad was born of a single act of imperial will. Around 100 AD, the emperor Trajan ordered a new colony to be founded in North Africa, on the southern frontier of the Empire, at the foot of the Aurès mountains. He named it Colonia Marciana Traiana Thamugadi, in honour of his sister Marciana and of himself.
The aim was twofold. On one hand, it would settle and reward the veterans of the Legio III Augusta, the legion garrisoning this region, by giving them land and a city to retire to. On the other, it would Romanise and control the Berber territory along the frontier, serving as a bulwark against the tribes of the interior and as a hub for spreading Roman culture. In that sense, Timgad was as much a political and military tool as it was a city.
Because it was built from nothing and in a short time, Roman engineers were able to apply their urban ideal without the constraints of land that was already occupied. They designed a perfect grid plan, inspired by the layout of military camps (the 'castrum'). Two main streets, the cardo (north-south) and the decumanus (east-west), crossed in the centre next to the forum, and a regular grid of square blocks surrounded them. That textbook plan is Timgad's greatest treasure today.
Timgad prospered quickly. The original city, planned for a few thousand inhabitants, soon became too small and grew beyond its first walled perimeter, spilling over the grid with new neighbourhoods, temples and buildings. At its peak, between the 2nd and 4th centuries, it may have housed around 10,000 to 15,000 people and became a thriving urban centre of the province of Numidia.
The city had every amenity of Roman life: a colonnaded forum with its basilica and curia, a theatre for about 3,500 spectators dug into a hillside, several bath complexes, markets and temples. Among the temples was a large Capitol dedicated to Jupiter, Juno and Minerva. As a notable rarity, there was also a public library donated by a wealthy citizen. The homes of well-off families were decorated with beautiful mosaics, many of which are kept today in the site museum.
The triumphal arch dedicated to Trajan, raised over the western decumanus, symbolised the pride and prosperity of the colony. The famous inscription found in the forum, 'To hunt, to bathe, to play, to laugh: that is living', sums up the spirit of well-being and leisure of that society. Timgad was the very picture of the Roman urban model's success, transplanted to Africa.
Like all of Roman North Africa, Timgad became Christian from the 3rd and 4th centuries onwards. The city came to have basilicas and a large Christian community. It was also one of the centres of Donatism, a Christian schism deeply rooted in North Africa that for decades set the region's Christians against the official Church of the Empire. Timgad was even the seat of a Donatist bishop, and religious disputes shaped its life in the Late Empire.
From the 5th century, the crises of the Roman Empire made themselves felt. The Vandal invasion of North Africa (from 429 onwards) and the weakening of imperial power left cities like Timgad more exposed. In the 5th century the city was sacked by Berber tribes from the Aurès mountains, a blow from which it never fully recovered.
There was a partial recovery in the Byzantine period, after Justinian's reconquest in the 6th century, when the Byzantines built a fortress next to the city to control the region. But Timgad had already lost its splendour. With the arrival of Islam in the 7th century and the upheavals that followed, the city was gradually abandoned, its inhabitants scattered and its buildings began to fall into ruin.
After it was abandoned, Timgad met a fate that, paradoxically, saved it. Many ancient cities were reoccupied, rebuilt and transformed by later civilisations, with their stones reused and their plans erased. Timgad was not. It was left empty in the middle of the plain and was slowly covered by sand blown in from the nearby Sahara.
For more than a thousand years, the city lay buried and almost forgotten, protected by the sand that covered it. That blanket shielded it from erosion, from systematic plundering and from new buildings being laid on top, freezing its Roman layout just as it had been left. It is the same reason Pompeii, buried by volcanic ash, survived so well, and it is why Timgad is nicknamed 'the Pompeii of Africa'.
It was rediscovered in the 19th century. In 1881, under French colonial rule, systematic archaeological excavations began and brought the buried city to light, street by street: the Arch of Trajan, the forum, the theatre, the baths, the library and the houses with their mosaics. Little by little, Timgad emerged from the sand as the most complete record of Roman town planning in North Africa.
In 1982, UNESCO added Timgad to the World Heritage List, recognising it as an exceptional and especially complete example of Roman town planning. No other site shows so clearly the orthogonal plan of Roman colonies, with its cardo and decumanus, its central forum and its grid of streets. It also shows how the city later grew beyond its original perimeter.
Timgad's value lies precisely in how intact it is. Because it was abandoned and never rebuilt, it gives a very clear picture of how a provincial Roman city was conceived and lived in. The Arch of Trajan, the theatre, the library, the baths, the Capitol and the mosaics in the museum make the whole site a true open-air textbook of archaeology and history, one of a kind.
Today Timgad and nearby Djémila are the two great Roman gems of north-eastern Algeria, and Timgad is one of the most impressive archaeological sites in the Mediterranean. It gets fewer visitors than other major sites of the Roman world, which gives it a feel of discovery, almost in solitude. For travellers who make it to the Aurès, it is an unforgettable experience: walking the paved streets of a 2,000-year-old city, with the Arch of Trajan standing out against the sky and the mountains in the background.
