Greeks settled in the cities of Pompeii and Herculaneum soon after it was established and both cities conducted many trades with the Egyptians. It is widely evident that the Greek and Egyptian cultures had a significant influence on the cities of Pompeii and Herculaneum in various ways including architecture, religion, art and literature.

Theatres in both Pompeii and Herculaneum show traits of Greek architecture. The large theatre in Pompeii is set into the slope of a hill just as classic Greek theatres were. The theatre in Herculaneum also resembles classic Greek theatres but it is supported by archways.
