Just to give you an idea, the Phoenicians of Tyre founded sites on Malta, Cadiz (southern Spain) and the entire north-west African empire of Carthage, with it's few isolated city-states. The Tartessians derived from them. They would have left multiple sites on the island of Malta, 5 or so cities on libya's Mediterranean coast, another 5 or so on the Tunisian coast, same for coastal Algeria and 3 sites on the Moroccan coas, whereas southern Spain by the north-African coast has 8 or so Phoenician colonies. Ibiza was colonized and southern Sardinia has 4 Phoenician colonies. Western Sicily had numerous Phoenician colonies as well.
