The Mosque of Three Doors is also worth visiting though tourists can only visit the outside.
Most Tunisians identify themselves as Arab though and the language is a Tunisian Arabic Dialect with many Berber influences and borrowed words.
The Berber language however is still spoken in places in Tunisia, primarily in remote mountain and Saharan areas.
There is a small European population, mainly French and Italians, and Jewish population as well.
Religion follows a similar balance with 98% of the population Muslims, as well as around 1% Christians and 1% Jewish; of those giving their religion as Muslim the majority are Sunnis.
Later Justinian sent his Byzantine armies to recapture Tunisia from the Vandals in 553 AD and took the cities of the area back with few problems and finding the cities far from vandalised by the Vandals in fact maintained and kept in much the way the Roman Empire had left them.
Arabian armies spreading the Islamic faith eventually pushed out the Christian Byzantines and spread their religion, though Arabs and Berbers fought for control for much of the next thousand years, the result was that the area became split between different tribes though Islam slowly became dominant.
Of course the beautiful, usually sandy, coastline is a major attraction but the interior of the country going down to the edges of the Sahara and the across to the Atlas mountains should also be explored by those with a sense of adventure and there is enough to keep history buffs transfixed for weeks.
The first thriving centres of culture in Tunisia were the Phoenician cities with Carthage founded in 814BC.
Though there were other Phoenician cities that remained independent the Carthaginian empire started to spread and flourish, absorbing many other cities.
