Bulla Regia is one of the most archaeologically important Roman towns in North Africa, located approximately 8km northeast of Jendouba, on the edge of Tunisia’s fertile Great Plains. It is a city shaped by Numidian, Punic, Roman, Byzantine, and early Islamic influences. Bulla Regia flourished due to its rich agricultural wealth, strategic location, and integration into the Mediterranean trade network. Today, the site is renowned for its unique underground villas, which were built by the Romans in the 2nd and 3rd centuries AD as a means to escape the fierce heat of the Tunisian sun and are decorated with mosaics.
Bulla Regia originated as a Numidian city influenced by Carthage. In 202 BCE, the Roman general Scipio Africanus captured the town, and it later became a royal residence for the Numidian king Massinissa. After the fall of Carthage, Bulla Regia was annexed to Africa Nova in 46 BCE following the defeat of Juba I. Under Roman rule, the city flourished, receiving municipal privileges from Julius Caesar and later becoming a colony under Hadrian, officially named Colonia Aelia Hadriana Augusta Bulla Regia.
Bulla Regia’s prosperity came from the fertile Great Plains, which supported wealthy elites who rose to equestrian and senatorial ranks. Bulla Regia was richly adorned with monuments, statues, and mosaics, while its streets, drainage systems, and public spaces reflected the Roman urban planning tradition. Notably, its private houses featured underground rooms, which were adapted to the hot climate. Many of these houses survive with their mosaics in situ, protected by the earth above them.
In late antiquity, Bulla Regia prospered under Vandal and Byzantine rule, as shown by coin hoards, fortified structures, and churches. Christianity was established, with bishops noted as early as the 3rd century, and St. Augustine preached there in 399. The presence of churches, cemeteries, and mosaics indicates a vibrant community that lasted into the 7th century AD. However, the city declined due to “ruralization,” with limited finds from the Islamic period. Bulla Regia was fully abandoned by the late 12th century, after which Jendouba became the new regional centre.
The site also includes temples, baths, a fort and a market square, but it is the houses which are the main attraction. Each of the villas has been named after the mosaics that were found within them. Some of these beautiful mosaics are still in situ, while others have been moved to museums such as the Bardo in Tunis.

Sbeitla is a small town located in west-central Tunisia, near the modern city of Kasserine, and is home to the ancient Roman town of Sufetula. Initially established as a municipium, a self-governing city with partial Roman citizenship, it was later elevated to the status of a Roman colony within the province of Africa Proconsularis. By the 3rd century AD, Christianity had established a strong presence in the area, and many of the churches visible today date back to this period, especially after the city became part of the newly created province of Byzacena. The ruins of Sufetula are remarkably well-preserved and include an impressive forum, public baths, several churches, and a unique Capitolium complex composed of three separate temples dedicated to Juno, Jupiter, and Minerva.
Although the early history of Sufetula is not well-documented, it is generally believed to have been founded in the 1st century AD, possibly under Emperor Vespasian. The city’s name may derive from the term ‘sufetes’, a Punic title used for magistrates in Carthaginian towns. Sufetula rose to prominence as a Roman colonia during the reigns of Antoninus Pius and Marcus Aurelius, and later became an important Christian centre under Byzantine rule. Inscriptions suggest that the city remained prosperous well after the fall of the Western Roman Empire, thanks largely to its thriving agricultural economy, particularly olive oil production.
The town played a significant role in the history of Roman Africa and later became the site of a heroic struggle for dominance between Christians and Muslims in the region. During this period, Byzantine Africa played a crucial role in supplying Constantinople with corn and olive oil. Although Emperor Heraclius had successfully repelled the Sassanid Persian Empire in the east, a new challenge arose from the Arabian Peninsula, where the tribes had united under the banner of Islam.

In 647 AD, Sufetula was conquered by Muslim forces led by Abdullah ibn Sa‘ad during the early Islamic expansion into North Africa. Although the city never regained its former Roman and Byzantine stature, the Islamic conquest marked the beginning of the region’s gradual Arabization and Islamization. Sufetula’s importance waned thereafter, as newer urban centres emerged under Islamic rule.
Because no modern settlement was built directly over ancient Sufetula, the Roman city plan remains exceptionally well-preserved, particularly the Forum, which is considered one of the best-preserved in the Roman world. This rectangular-walled enclosure measures approximately 72 by 60 meters (238 by 197 feet) with a monumental gateway at the centre of one side, and smaller entrances on the remaining three. Opposite the main entrance stand three imposing temples, believed to be dedicated (from right to left) to Juno, Jupiter, and Minerva. Opposite this gate, across the vast, almost square Forum, stand three massive temples that are believed to be dedicated (from right to left) to Juno, Jupiter, and Minerva.
The entrance gateway was dedicated to Antoninus Pius, as recorded in an inscription in the frieze, though the lettering is heavily eroded and only partially legible today.

Beyond the Forum, visitors can explore numerous well-preserved structures that reflect the city’s rich history and vitality. These include public baths, a basilica, and a Byzantine church. The presence of Christian monuments, such as chapels and baptisteries, underscores Sufetula’s importance in the early Christian era. Additionally, remnants of homes, paved streets, and water systems offer a rare and vivid glimpse into daily life in a Roman provincial city.
