Mix of imagination and some ruins, i guess. Original Carthaginian port is visible even today, together with that little "island" in the middle. Some Punic (not Roman) ruins are black even today because of fire...

Yes, it's beautiful... 2 pictures only, but enough for people with imagination... When i look at them, i have a feeling like i'm there, in the past... i hear waves and sea-gulls in the air....
