Northwestern Tunisia is renowned for its rich archaeological heritage and historical diversity, reflecting the succession of civilizations that have passed through the region—from Berber and Carthaginian to Roman, Byzantine, and Arab. Some of the most important archaeological sites include:

In Béja Governorate:

Dougga:

Dougga is one of the most important and best-preserved Roman cities in North Africa, and it is listed as a UNESCO World Heritage site. It features an impressive collection of landmarks such as the Roman theater, the Capitol temple, the public forum, and numerous tombs and cemeteries.

Testour:

Testour is a city with a distinctive Andalusian character, founded by Andalusian immigrants. It is known for its unique architecture and its ancient mosque, which features an extraordinary clock.



In Jendouba Governorate:

Bulla Regia:

Bulla Regia is distinguished by its underground Roman houses, which were used to protect inhabitants from the summer heat. It is also famous for its three-dimensional mosaic floors.

Tabarka Castle:

An ancient historic fortress built around a thousand years ago, notable for its military design and strategic location on a small island.

Chemtou:

Chemtou (also known historically as Khmītu or ancient Simitthu) is a historic archaeological site located in northwestern Tunisia, near the city of Jendouba. During the Roman era, it was famous as one of the main sources of Numidian yellow marble (also known as Giallo Antico or "ancient yellow"), which was used to decorate major monuments in Rome and throughout the Roman Empire.

In Siliana Governorate:

Maktar:

A large archaeological site that includes remains from various periods, ranging from prehistoric dolmens to Roman ruins, including baths, a theater, and temples.



In the governorate of El Kef:

Kasbah of El Kef:

It was built during the Ottoman period, specifically in the 17th century, when El Kef was an important administrative and military center in the Tunisian province (Eyalet).

It served as a military fortress to protect the city from attacks coming from the west (especially from Algeria and Morocco). It was also the headquarters of the Ottoman military garrison and a center of administration.

The Basilica:

The local name is Dar El Kous (دار القوس / “House of the Arch”); the French name is Basilique Saint-Pierre du Kef.

It was likely built on the site of an ancient Roman temple or using materials from earlier Roman structures.

During the French protectorate in Tunisia, it was used as a place of Christian worship until it was closed around the mid-20th century (approximately in 1964).

Jugurtha's Table:

Jugurtha’s Table is located near the fertile town of Kalaat Senan in the governorate of El Kef, close to the Tunisian-Algerian border.

It is named after King Jugurtha, a famous Numidian king (118–105 BC) who bravely resisted the Romans. According to legend, he took refuge on this plateau during his struggle against Roman forces.

The site is believed to have been used as a defensive position or a natural refuge by the Numidian army.
