Renowned as home to one of the world's greatest trading empires, Carthage was established as far back as 9BC by Phoenician traders and its power over the Mediterranean forged an advanced civilisation and large and rich city. Today the city is located on the eastern side of Lake Tunis, across from the capital of Tunisia, Tunis. Carthage's extensive archaeological site is today a UNESCO World Heritage Site and popular tourist attraction displaying the blossoming of several cultures - Phoenico-Punic, Roman, Paleochristian and Arab - that made this city the central hub in the Western Mediterranean. It remains renowned as one of the most famous historic sites of the Roman Empire. An additional tourist attraction is the 1890 Cathedral of St Louis, located on the hill overlooking the city, where French King Louis IX died in 1270.
