Carthage

 place with historical importance, UNESCO World Heritage Site

Once one of the greatest cities in the world, Carthage claimed a large empire by the 3rd century BC and was a center of trade throughout the Mediterranean. It was founded by the Phoenicians from Tyre in the 9th century BC. Due to its position, it was able to control trade routes that went through the area between N. Africa and Sicily.

After three brutal wars with the Romans, they were finally defeated and Rome took over. Carthage remained an important city for almost a thousand more years under the Romans, then the Vandals, and finally the Byzantines. The city lost its status as the capital of the region when it was destroyed in 698AD. Power shifted to Tunis as the major city.

In February 1985, Ugo Vetere, the mayor of Rome, and Chedly Klibi, the mayor of Carthage, signed a symbolic treaty "officially" ending the conflict between their cities, which had been supposedly extended by the lack of a peace treaty for more than 2100 years.
