Passage: Alexandria is believed to have been founded by Alexander the Great in April 331 BC as Ἀλεξάνδρεια (Alexandreia). Alexander's chief architect for the project was Dinocrates. Alexandria was intended to supersede Naucratis as a Hellenistic center in Egypt, and to be the link between Greece and the rich Nile valley. Although it has long been believed only a small village there, recent radiocarbon dating of seashell fragments and lead contamination show significant human activity at the location for two millennia preceding Alexandria's founding.Alexandria was the intellectual and cultural center of the ancient world for some time. The city and its museum attracted many of the greatest scholars, including Greeks, Jews and Syrians. The city was later plundered and lost its significance.In the early Christian Church, the city was the center of the Patriarchate of Alexandria, which was one of the major centers of early Christianity in the Eastern Roman Empire. In the modern world, the Coptic Orthodox Church and the Greek Orthodox Church of Alexandria both lay claim to this ancient heritage.

Question: Which city was found to have activity long before it was actually founded?
